Description

  The present invention relates to a seismic response analysis model of a unit type building composed of a plurality of building units and a seismic response analysis system of a unit type building, in particular, by using a non-structural member other than a structural member as a constituent member of the model, The present invention relates to an earthquake response analysis model and an earthquake response analysis system that can improve the analysis accuracy by simple modeling.

  For small and medium-sized general buildings, as a method of evaluating the safety of buildings against earthquakes, the stress generated in the model components when static external forces are loaded in each direction of the building model is calculated. Safety is evaluated based on whether the calculated stress is within the allowable stress level or the material strength. The building model here is generally a plurality of two-dimensional models composed of a longitudinal section and a transverse section of the building, and the stress is calculated by loading a static external force for each section.

  On the other hand, in large-scale high-rise buildings and special structure buildings equipped with dampers or seismic isolation devices, the analysis model is modeled not only in two dimensions but also in three dimensions, and as expected at the construction site or area. The seismic waveform is created or selected and, for example, by inputting the seismic waveform statically or dynamically into a three-dimensional analysis model, the degree of damage or the possibility of collapse of each part of the building is evaluated.

  Here, as shown in FIG. 16, the method generally used as the modeling method of the building used for the latter seismic response analysis is to replace the weight of each floor with mass points a1 and a2 consisting of masses of weights. The deformation performance and the restoring force characteristic are the methods of replacing the springs b1 and b2 having the rigidity of the building and the dashpots c1 and c2 having the damping characteristic (so-called skewer dumpling model). By inputting, for example, a dynamic earthquake waveform to such a model, the stress and deformation of each floor (each mass point on the model) can be calculated in time series.

  The above-mentioned so-called skewer dumpling model ignores the deformation performance and changes of each structural member constituting the building, and it becomes a simplified model for each hierarchy, so it is easy to create a model, If the estimation of parameters set when creating the model deviates from the parameters of the actual structure, the accuracy of the analysis result will be extremely low.

By the way, in patent document 1, the invention regarding the unit type building which made one structure surface of the building unit arranged side by side one continuous plane structure, and its structural calculation method is disclosed. For example, when the building unit has a ramen structure, the unit type building model created at the time of the structural calculation is configured only from columns and beams that are structural members constituting the ramen structure. By applying a static external force (X direction and Y direction) in one plane to this model, the stress and deformation amount of the members constituting the unit type building (building unit) are calculated. In such a model, the deformation performance of the unit type building at the time of earthquake and the attenuation of the seismic energy are not taken into consideration, and therefore the analysis result is generally a structural calculation on the safe side. In other words, in addition to the non-linear characteristics inherent to unit type buildings, non-structural members such as center pillars, outer walls, and inner walls are not reflected in the model, so structural members bear all external forces for the set external force. As a result of the structural calculation such as, the structural member is excessively designed.

  The seismic response analysis model and the seismic response analysis system of the present invention are made in view of the above-described problems, and connect a plurality of seismic response analysis models of building units having not only structural members but also non-structural members. The purpose is to provide a seismic response analysis model for a unit building that can improve the analysis accuracy while achieving simple modeling. It is another object of the present invention to provide an earthquake response analysis model that can easily replace an earthquake response analysis model of a created unit type building with an earthquake response analysis model of a general building other than the unit format. In addition, an earthquake response analysis system that enables earthquake response analysis of buildings according to construction points by systematizing the analysis while making it possible to update member information data and input earthquake data used for earthquake response analysis at any time. The purpose is to provide.

  To achieve the above object, an earthquake response analysis model according to the invention of claim 1 is an earthquake response analysis model of a unit type building formed by connecting earthquake response analysis models of a plurality of building units. The unit type building seismic response analysis model comprises a structural member modeled as a wire or a face material and a non-structural member other than a structural member modeled as a wire or a face material. .

  The present invention relates to a seismic response analysis model of a unit building constructed by connecting a plurality of building units. In conventional analysis models, only structural members such as beams, columns, and seismic walls are components of the analysis model, and so-called non-structural members such as middle columns, outer walls, and inner walls are not expected as components of the analysis model. It was. According to the seismic response analysis based on such an analysis model, while it becomes a structural design on the safe side, it is not necessary to evaluate the actual proof stress (including actual deformation performance) of the structure including non-structural members. As a result, an oversized structure was to be created.

  Since the present invention is intended for unit-type buildings composed of a plurality of building units, if modeling of structural members and non-structural members that are constituent members of a building unit, modeling of the entire unit-type building Only needs to connect as many building unit models as necessary, so modeling is relatively easy.

  Here, as an embodiment for modeling the face material, for example, there is modeling in which the face is replaced with two wire materials.

  As the earthquake response analysis model, a three-dimensional model is mainly targeted, but it goes without saying that the two-dimensional model is not excluded.

  Further, the earthquake response analysis model according to the invention of claim 2 is formed as a structural unit of a building unit, and a columnar material or a beam material is modeled as a wire material, thereby forming an earthquake response analysis model of a building unit having a ramen structure. The seismic response analysis model formed by connecting the seismic response analysis models of a plurality of the building units, wherein the seismic response analysis model of the unit type building is a non-structural member other than the structural member The columnar material and / or the wall material are each modeled as a wire material or a surface material, and are formed by joining the wire material or the surface material to the wire material of the structural member.

  The seismic response analysis model of the present invention relates to a seismic response analysis model of a unit type building constituted by connecting a plurality of analysis models of a plurality of ramen structure building units.

  Here, the structural member in the ramen structure is a pillar material and a beam material constituting the ramen structure, and the non-structural member is a middle pillar, outer wall, inner wall, or partition wall other than the ramen structure constituent member.

  Both structural members and non-structural members have material characteristics and member rigidity for each member. Here, examples of material characteristics include Young's modulus, linear expansion coefficient, linear characteristics, and nonlinear characteristics. Examples of the member rigidity include a cross-sectional area uniquely determined from a cross-sectional dimension and a cross-sectional secondary moment.

  In the earthquake response analysis model of the present invention, the beams and columns of the structural members constituting the ramen-structured building unit are modeled three-dimensionally as wire rods. Modeling is achieved by connecting to a structural member constituting a three-dimensional model as a face material. The analysis is performed in a computer, and such modeling is also performed in the computer. The material characteristics and member rigidity of each structural member and non-structural member are input into a dedicated input sheet in the computer. The

  As described above, the seismic response analysis model of the present invention creates a seismic response analysis model of a unit type building by connecting a plurality of ramen structure building units, and if the building unit is modeled, After that, since it is the work of connecting only the necessary number of building unit models, modeling is relatively easy even if non-structural members are modeled. In addition, when connecting building units, the connection material which can transmit the horizontal force at the time of an earthquake, etc. should just be used suitably.

  The earthquake response analysis model according to the invention of claim 3 is a building unit having a wall-type structure in which a floor material, which is a structural member of a building unit, is modeled as a wire, and a wall material is modeled as a face material. The seismic response analysis model is formed by connecting the seismic response analysis models of the plurality of building units, and the unit type building seismic response analysis model has the structure Columns and / or wall materials, which are non-structural members other than members, are modeled as wires or face materials, respectively, and formed by joining the wire materials or the face materials to the wire materials and face materials of the structural members. It is characterized by being.

  The present invention relates to a seismic response analysis model for a unit type building constituted by connecting a plurality of building units having a wall type structure.

  Here, the wall-type structure is basically a structure type constituted by a structural member made of a floor material and a wall material, unlike a ramen structure in which a frame is made up of beams, columns, and the like.

  The floor material is modeled by connecting the wire materials at their respective ends, the wall material is modeled as a face material, and the edge of the face material of the wall material model is connected to the wire material of the floor material model. In the present invention, a building unit model is formed by connecting a non-structural member, which is a non-structural member, as a wire, and an outer wall, an inner wall, a partition wall, etc., as a face member, and a structural member, and connecting the necessary number of such building unit models. The seismic response analysis model of a unit type building is constructed.

  Further, in the earthquake response analysis model according to the invention of claim 4, the wire and the face material have a spring having a member rigidity that can be reduced in accordance with the deformation of the building during an earthquake, and a dashpot capable of attenuating earthquake energy. And.

  The face material can be modeled as a material point having the weight of the wall, in addition to replacing the two wire materials as described above. In this case, it becomes a model in which a wire is attached above and below the mass point. When modeling an analysis model, the analysis model is equipped with a spring in which the rigidity of the member is replaced with a wire such as a beam or column, and a dashpot that evaluates the attenuation of seismic energy when the building is deformed By doing so, an analysis model in which the deformation of the building (actual behavior of the building) is appropriately reflected can be created. Note that the above-described springs and dashpots can be modeled as springs and dashpots that take into account the joint structure, for example, at a joint portion between a wire rod modeled with a beam and a wire rod modeled with a column.

  An earthquake response analysis model according to the invention of claim 5 is an earthquake response analysis model of a general building created from the earthquake response analysis model of the unit type building, and constitutes the earthquake response analysis model of the unit type building Among the seismic response analysis models of the building units to be constructed, adjacent structural members or structural members and non-structural members of the seismic response analysis model are replaced with one composite member, and the member rigidity of the composite member is synthesized.

This is suitable when an analysis model is created and then changed to an earthquake response analysis model of another general building. For such changes, in addition to changing the input conditions such as the cross-sectional performance of structural members and non-structural members that are constituent members, adjacent members of the seismic response analysis model of the building unit installed vertically or horizontally Need to be replaced with one composite member. Therefore, in this case, the external dimensions of the entire building are not changed by adopting a model in which the composite member is arranged at the center position of the adjacent member models, and moreover, a plurality of the composite members before the composite member is combined with the rigidity. Change to a rigidity equivalent to the overall rigidity of the members. Here, when the structural format of the seismic response analysis model of the unit type building originally created is the same as the structural format of both the earthquake response analysis model of the modified general building (for example, when both have a ramen structure) May be a composite member having rigidity equivalent to the overall rigidity composed of a plurality of members to be combined. On the other hand, when the structural form changes, such as changing from a ramen structure unit type building to a wooden frame structure building, in addition to the replacement of structural members, the requirements specified in the Building Standards Act and structural design guidelines, etc. It is necessary to use a composite member having the required rigidity in a state where the structural member (for example, a brace material) is disposed.

  An earthquake response analysis model according to the invention of claim 6 is an earthquake response analysis model of a general building created from the earthquake response analysis model of the unit type building, and constitutes an earthquake response analysis model of the unit type building Among the seismic response analysis models of the building units to be constructed, adjacent structural members or structural members and non-structural members of the seismic response analysis model are replaced with one composite member, and the member rigidity of the composite member is synthesized. The overall rigidity of the plurality of members is increased rigidity or reduced rigidity.

  When changing from a seismic response analysis model of a unit type building to a seismic response analysis model of a general building, the rigidity (cross-sectional performance, etc.) of the original structural member or non-structural member shall be increased or decreased at a certain rate. You can also. For example, adjustment is performed while increasing or decreasing the rigidity of each member so that the strength against the static load of the seismic response analysis model after the change is comparable to the strength before the change. In this case, for example, in the grades stipulated in the “Law on Promotion of Housing Quality Assurance” and related structural laws, etc., the buildings are replaced between different grades and compared. You can also.

  In the earthquake response analysis model according to the invention of claim 7, a specific deformation amount and / or load limit value is set for each of the wire and / or the face material, and the deformation amount and the load are set. Is characterized in that stress is not transmitted to the wire or face material exceeding the limit value.

  In the member characteristics of structural members and non-structural members that make up the seismic response analysis model, the limit value of deformation and acting load is preset, and if this limit value is exceeded, the member will be used in subsequent analysis. It is possible to reproduce the collapse behavior of the building in a more realistic form by configuring so that no stress is transmitted to the.

  In the earthquake response analysis model according to the invention described in claim 8, the floor material, which is a structural member of the building unit, uses a frame material constituting the floor material as a wire material, and a panel material attached to the frame material as a face material. The wall material, which is a structural member, is modeled as a frame material constituting the wall material as a wire material, and a panel material attached to the frame material as a face material. The seismic response analysis model according to claim 1, wherein an earthquake response analysis model is formed and the seismic response analysis models of a plurality of the building units are connected to each other. In the model, columnar materials and / or wall materials, which are non-structural members other than the structural members, are modeled as wire rods or face materials, respectively. Is formed by being stitched with product, the surface material of at least the panel member is modeled, characterized in that it comprises a member rigid with the said panel.

  The present invention relates to a seismic response analysis model for a unit-type building, which is formed by connecting a plurality of analysis models of a building unit having a frame wall structure such as a so-called 2 × 4 (two-by-four) method or a 2 × 6 (two-by six) method. Is. The floor and the wall constituting the frame structure are configured in such a manner that a panel material is bonded to a frame material. Therefore, in the present invention, the frame material is modeled as a wire material, and the panel material is modeled as a face material. Here, the face material on which the panel material is modeled can be constituted by, for example, an H-shaped wire connected to a frame material model (wire material) surrounding the face material model. For example, in the case where a plurality of frame members for a vertical beam are provided in a frame member having a rectangular outer shell, each panel member is modeled in each rectangular frame surrounded by the frame member and the vertical beam. H-shaped wire rod model can be connected. In addition, the panel material modeled with the panel material has member rigidity (in-plane rigidity or out-of-plane rigidity) that takes into account the thickness of the panel, etc., so that the strength of the framed wall structure building during earthquake is appropriate. The model reflected in can be configured.

  Further, the earthquake response analysis model according to the invention of claim 9 is such that the member rigidity of the wire material obtained by modeling the frame material is extremely higher than the member rigidity of a face material obtained by modeling the panel material. It is characterized by being set to a small value.

  The present invention relates to a seismic response analysis model of a unit type building constructed by connecting a plurality of analysis models of a building unit having a frame wall structure as described above, and the rigidity of a frame member whose rigidity is extremely small compared to a panel member. It is intended to realize seismic response analysis calculation on the safe side by setting it extremely small. Here, the member rigidity of the wire rod modeled from the frame material is set to a value that is extremely smaller than the member rigidity of the face member modeled from the panel material. This means measures such as setting the rigidity of the frame material model to a value that is as close to zero as possible within the range in which the seismic response analysis can be performed in the computer.

  Further, in the earthquake response analysis model according to the invention of claim 10, when the panel material is provided with an opening, the member rigidity of the panel material is a member rigidity reduced by the opening. To do.

  In particular, since an opening is provided in the panel material constituting the wall, the accuracy of the analysis result can be improved by appropriately evaluating the decrease in rigidity of the panel material due to the opening. In addition, in the framed wall structure, the specifications of the walls and floors (material, size, shape, etc.) are uniformly defined, and the positions and number of openings are almost uniformly defined. Once the rigidity of the panel material is determined, it can be used widely.

  The earthquake response analysis system according to the invention of claim 11 inputs the input earthquake information of the construction site of the unit type building or the vicinity thereof into the earthquake response analysis model of the unit type building composed of a plurality of building units. An earthquake response analysis system for performing an earthquake response analysis of a unit type building, wherein the earthquake response analysis system stores member information data of structural members and non-structural members constituting an earthquake response analysis model of a building unit. A member information means for storing, an earthquake information means for storing input earthquake data, an earthquake response analysis model is created based on the member information means, and the required input earthquake data extracted from the earthquake information means is used as the earthquake response analysis model. And an analysis means for performing an earthquake response analysis by inputting the earthquake response analysis system. However, the information from the member information means and the earthquake information means can be collected by the communication means, and the member information data in the member information means and the input earthquake data in the earthquake information means are updated as needed. To do.

  In this system, for example, an analysis means is provided in a computer on the central manager side, and a member information means and an earthquake information means are provided in computers in branches or sales offices throughout the country. Information is exchanged between the administrator side and the branch offices in various places through communication means.

  The earthquake information means in the computer of each branch (or sales office) stores past earthquake record waveform data in each region or each branch's jurisdiction region and synthesized earthquake waveform data unique to each region. This earthquake record waveform data and the like are added every time the latest earthquake record is obtained for each region.

  On the other hand, the member information means in the computer of each branch stores, for example, member information data for building a unit type building that can be obtained in each region. This member information data is also added to the member information means as the latest data when, for example, a new member becomes commercially available.

  When a branch office or sales office in each region requests a central manager to review the structure of a unit-type building, the central manager obtains the necessary input earthquake data from the requesting branch's computer via communication means. Select input earthquake data to be used for analysis. Next, the central manager creates an earthquake response analysis model based on the layout of the unit type building according to the needs in the analysis means in the computer. For example, at the stage when the three-dimensional model is created, each member of the structural member and the non-structural member constituting the analysis model of the building unit is selected based on the member information data obtained through the communication means.

  The seismic response analysis is carried out while loading the selected input seismic data on the analysis model. As a result of the analysis, if the strength of the unit type building is insufficient or excessively designed, the member is selected again and the earthquake response analysis is performed again. In some cases, by repeating such a flow, it is possible to obtain an accurate seismic response analysis result reflecting the seismic data specific to the construction point of the unit type building or the planned construction point. According to the present invention, member data available in a region and region-specific earthquake data can be easily used at the time of analysis, so that an optimal structural design can be performed in a short time.

  In addition to the earthquake information means, the earthquake response analysis system according to the twelfth aspect of the invention further includes load information means including at least wind load information and snow load information for each region. Is characterized in that structural analysis is performed by loading wind load and / or snow load on the earthquake response analysis model in addition to earthquake response analysis.

It is about. The wind load data and the snow load data are also stored in the computer of the branch office of the requester in the same manner as the input earthquake data, and the central manager can obtain them by communication means. Such load data can use values for each region that have already been set by the Building Standards Act and related laws and regulations.

  The earthquake response analysis system of the present invention can be applied not only to a unit type building but also to a general building described above (a general building earthquake response analysis model changed from a unit type building earthquake response analysis model). In addition, by inputting the place name, administrative code, longitude and latitude on the computer on the central manager side, various design information (earthquake-resistant design conditions, wind-resistant design conditions, snow-resistant design, etc.) from each branch office and sales office An embodiment in which conditions are automatically transmitted to the central manager and the building structure is selected and analyzed is also applicable.

  Furthermore, the earthquake response analysis system according to the invention described in claim 13 is characterized in that the earthquake response analysis model is the earthquake response analysis model according to any one of claims 1 to 10.

  As can be understood from the above description, according to the seismic response analysis model of the present invention, not only structural members but also non-structural members are reflected in the analytical model, so that the analysis accuracy can be improved. In addition, according to the earthquake response analysis model of the present invention, since the reduction of the rigidity of the member and the attenuation of the earthquake energy during the earthquake are further evaluated, the analysis accuracy can be further improved. In addition, since the earthquake response analysis model of the present invention is intended for a unit type building in which a plurality of building units are connected, a model can be created relatively easily even if a non-structural member is incorporated in the component of the analysis model. it can. In addition, according to the earthquake response analysis model of the present invention, it is possible to easily change the earthquake response analysis model of a unit type building to an earthquake response analysis model of a general building, and accordingly, the earthquake response of a building of any structural type. It can be applied to analysis. Furthermore, according to the earthquake response analysis system of the present invention, it is possible to perform an earthquake response analysis based on input earthquake data specific to a construction area or a planned construction area and member information data available in the area. Since such data is updated from time to time, it is possible to carry out more realistic structural calculations of unit buildings.

Further, based on the connection structure between the column member 2 and the beam member 3, a spring 41 and a dashpot 42 are modeled at the connection portion. In the embodiment of FIG. 1, the outer wall a indicated by a two-dot chain line is modeled by two wire rods 5 and 5, and the connecting portion between the outer wall a and the beam member 3 is similar to the connecting portion of the structural member. The spring 51 and the dashpot 52 are modeled.

  Here, in setting the rigidity (deformation performance) of the members constituting the building unit, a load-deformation characteristic as shown in FIG. 2 can be used. In the present invention, the conventional polygonal line X indicating the load-deformation characteristic can also be used as a smooth load-deformation characteristic line Y taking into account the actual gentle member yield.

  FIG. 4 shows an embodiment of a unit building analysis model 10 configured by connecting a plurality of building unit analysis models 1 shown in FIG. 1 in the horizontal direction and the vertical direction.

  When the analysis model 10 of a required unit type building is constructed, the analysis models 1 and 1 of adjacent building units need only be connected by the connecting material 7 that can transmit the horizontal force at the time of input earthquake loading. In the computer, by loading required input earthquake data on the analysis model 10 of the unit type building, stresses and deformation amounts generated in each member are output.

  FIG. 5 shows another embodiment of the building unit analysis model. In this analysis model 1a, the outer wall is not modeled as two wires, but the weight of the outer wall is replaced with a mass 5b, and the outer wall is modeled by connecting the wires 5a and 5a to the mass 5b. A spring 51a and a dash pot 52a are interposed at a connecting portion between the wire 5a and a wire 3 that is a model of a beam that is a structural member.

The spring wire 41 and the dashpot 42 are provided in the wire rod model of the pillar material as the structural member, and the spring 51 and the dashpot 52 are provided in the wire rod model of the outer wall as the non-structural member, respectively.

  Next, an embodiment in which the analysis model of a unit type building is changed to an analysis model of a general building other than the unit type will be described with reference to FIG. The analysis model 10 shown in FIG. 7a is the same model as the analysis model 10 of the unit type building shown in FIG. 4, for example, and illustration of a spring, a dashpot, etc. is omitted here. FIG. 7 b shows a model created by creating the structural model 10 of the unit type building having the ramen structure shown in FIG. 7 a and then changing the structural specification of the building to another structural specification without changing the external dimensions. In FIG. 7a, the adjacent wire rods 3 and 3 in the building unit analysis models 1 and 1 are replaced with one composite member (wire rod 3a) in FIG. 7b. The analysis model 11 shown in FIG. 7b is a model related to a wooden frame structure building, for example.

  FIG. 8 shows an embodiment of hysteresis showing the characteristics of the members constituting the analysis model for unit type buildings and the analysis model for general buildings described above, in which limit values are set for the load and the deformation amount. Since limit values are set for the load and deformation amount for each member, stress transmission will not be performed for members exceeding the limit value, and the analysis model will not consider such members in subsequent structural analysis. Analysis continues. By setting such member characteristics for each member, it is possible to realize a structural analysis in accordance with the actual collapse mechanism.

  FIG. 9 shows an embodiment of a plate material for walls and floors constituting a unit type building of a framed wall structure type. As shown in the figure, the plate material is composed of a frame material a1, a panel material a2 attached to the frame material a1, and a plurality of vertical bars a3, a3,... In the frame material. It is not limited. Since the frame material a1 and the panel material a2 are both made of wood and there are various detailed materials, material characteristics corresponding to the materials are set in modeling.

  FIG. 10 shows an embodiment in which the plate material of FIG. 9 is modeled for a structural model at the time of earthquake response analysis. In the frame material a1, the rating points of the wire rods 100, 100,... Are rigidly joined to each other, and a panel material modeled on the H-shaped wire rod 200 is attached therein. Note that the panel material can be modeled not only in such an H-shaped wire but also in an appropriate form such as a form in which the wires are crossed. Further, when modeling the plate material, the connection between the wire 100 and the H-shaped wire 200 is appropriately connected according to the actual connection strength and connection mode between the frame material and the panel material, such as modeling the connection portion as a laminated beam. A method may be applied.

  FIG. 10 shows a framed wall formed by connecting the plate models shown in FIG. 9 together to create a building unit analysis model 1b, and rigidly joining the plurality of analysis models 1b, 1b,... The structural model analysis model 10b of the unit type building of a structure type is shown. Although the modeled non-structural member is omitted in the illustrated analysis model 10b, modeling is performed as described above for a sleeve wall or an inner wall attached to an actual unit type building, and the analysis model is appropriately selected. What is necessary is just to connect with this structural member.

  In addition, when inputting the member characteristics (member rigidity) of the analysis model, it was selected by inputting the rigidity corresponding to the thickness of the panel material calculated in advance as a graph as shown in FIG. 12a. It is preferable that the rigidity according to the panel thickness can be automatically selected in the computer. Furthermore, when modeling a plate material for a wall, considering the existence of a wall having an opening for a window, the rigidity reduced by the opening is calculated in advance according to the occupation ratio of the opening, and the calculation result Is graphed as shown in FIG. 12b, it is possible to realize modeling with higher accuracy.

  If you want to obtain the seismic response analysis result on the safe side, set the rigidity of the panel material that constitutes the plate material as it is, and set the rigidity of the frame material to be able to execute the seismic response analysis in the computer. At the limit, it can be set to a very small value (a value close to zero). This is because most of the components that can be expected as the strength in earthquakes are the panel materials among the structural members of the framed wall structure building. However, compared with a frame structure building (such as the ramen structure described above), the horizontal force during an earthquake is countered by the surface of the floor or wall. It is also a feature, and even if the rigidity of the frame material is not taken into consideration, it is considered that there is no significant difference in the analysis results.

Next, an outline of the earthquake response analysis system will be described based on FIGS.
In the seismic response analysis system, a computer 100 on the central manager side and a computer 200 on a branch office or sales office side are connected by a communication line. The computer 100 contains analysis means 101 and communication means 102, and the computer 200 contains member information means 104, earthquake information means 105, communication means 103, and output means 106. .

  The member information means 104 and the earthquake information means 105 store member data that can be obtained in the respective regions and region-specific earthquake waveform data (earthquake record waveform data, composite earthquake waveform data). Data is updated and stored as needed by inputting the latest data 107 and 108. In addition, as member information data, cross-sectional performance, member rigidity, etc. are data-ized for every specification of a member.

  For example, when a unit building specification input 109 corresponding to a customer's needs is made at a sales office in an arbitrary region, this data is transmitted to the computer 100 on the central manager side via the communication means 103 and 102. . On the central manager side, an earthquake response analysis model is created in the computer 100 based on the specification data of the unit type building. Furthermore, member information data and appropriate input earthquake data are obtained from the computer 200 via the communication means 103 and 102, and an earthquake response analysis is performed based on these data.

An outline of one embodiment of the analysis means will be described based on the flow of FIG.
By inputting the construction site information input 110 to the computer 100, the data fetched from the computer 200 is narrowed down to the required area.

  Next, appropriate input seismic data selection 120 is performed from the input seismic data stored in the seismic information means 105 of the computer 200 based on the compliant design criteria.

  After selecting the input seismic data, an earthquake response analysis model of the unit type building is created 130 according to the specifications of the unit type building. As the earthquake response analysis model, for example, the analysis models 10 and 10a described above can be used.

  For example, after creating a three-dimensional analysis model, the selection 140 of the structural member and the non-structural member constituting the analysis model is performed. The member data is taken from the member information data stored in the member information means 104 of the computer 200. By selecting each member with the computer, the cross-sectional performance and member rigidity of each member are analyzed models. It will be added to.

  After creating the analysis model and selecting the component members, the seismic response analysis is performed by loading the selected input earthquake data into the analysis model.

  As a result of the seismic response analysis, a component with insufficient strength is generated, or conversely, if the calculation result is an excessive design, the member is selected again and the seismic response analysis is performed again.

  Based on appropriate criteria, the selection of members is repeated until the optimum design is achieved, and the earthquake response analysis is completed at the stage when the optimum design is achieved.

  According to the earthquake response analysis system described above, the earthquake response analysis can be performed based on the earthquake data peculiar to each region and the available member data. Can be provided. In addition, the actual seismic response analysis need only be performed by the central administrator, and therefore it is not necessary to have a technician who is familiar with seismic response analysis at each branch or sales office.

  FIG. 15 is a flow showing another embodiment of the analyzing means. First, an earthquake response analysis model is created after the construction site information input 210 (220), and load information means 201 which accumulates wind load information / snow load information, etc. specific to each region in the computer 200 of each branch or sales office. Load data from the central manager through the communication means, and based on the load data, wind resistance design, snow resistance design, and further, the primary design based on the allowable stress method, etc. The analysis model member selection 230 in the previous stage of the seismic response analysis is performed. Next, earthquake data is obtained from the earthquake information means 105 via communication means, and an earthquake response analysis 240 is performed based on the earthquake data. As a result of the seismic response analysis, a component with insufficient strength is generated, or conversely, if the calculation result is an excessive design, the structural specification of the building is changed and the seismic response analysis is performed again. The member selection is repeated until the optimum design is reached, and the earthquake response analysis is completed when the optimum design is achieved.

  The analysis means described above can be applied to the renovation and renovation design of existing buildings in addition to the structural analysis of new buildings.
