Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural calculation support system and program for structural calculation of a building.

Conventionally, when designing a building, structural calculations (strength studies) are performed at all times and during earthquakes, and the resistance and deformation of each part are calculated. A structural calculation support system (program) is used to perform such calculations. Structural calculation is performed by inputting necessary data into the system.

As such a structural calculation support system, for example, there is a design support system in which a design verification support device and a design change device exchange data by communication (Patent Document 1).

On the other hand, in structures, a deck plate that serves as both a concrete floor slab formwork and a structure may be used. In the conventional design support system, instead of inputting the rigidity value of the steel frame beam of the structure in the structural calculation of the structure using such a deck plate, the steel frame beam and concrete are integrated in advance. Structural calculation of the structure was performed by separately calculating the stiffness value of the composite beam (for example, Patent Document 2) and inputting this stiffness value.

Japanese Patent Application Laid-Open No. 2002-230045 JP 2012-12788 A

In such conventional structural design support systems, structural calculations are normally performed by inputting the types (size, shape, etc.) of beams and deck plates to be used. Therefore, for example, it is used as a means of selecting the type of beam or deck plate, looking at the structural calculation results, and determining whether or not it is suitable for the target structure.

In such a structural design support system, it is necessary to repeatedly input a lot of information used in calculations, such as the size of beams and deck plates used for each calculation condition. For this reason, it is required to omit the labor of inputting as much as possible. However, there are many types of beams and deck plates, and there is a risk that input errors may occur when inputting the types of beams and deck plates.

On the other hand, there is also a method in which a list of beams and deck plates is prepared in advance, and the types of beams and deck plates can be selected from the list, for example, in a pull-down format. However, even with this method, it takes time to search for the desired beam or deck plate from among the many types in the list.

FIG. 2 is a diagram showing the hardware configuration of a structural calculation support system 20; FIG. 4 is a flowchart showing processing of the structural calculation support system 20; 4 is a flowchart showing another process of the structural calculation support system 20; 4 is a flowchart showing another process of the structural calculation support system 20;

A structural calculation support system according to an embodiment of the present invention will be described below. FIG. 1 is a perspective view showing a deck plate 1. FIG. The deck plate 1 is composed of a plate 3, main reinforcing bars 5, auxiliary reinforcing bars 7, and the like.

The plate 3 is, for example, a steel plate formed with fine corrugations. A main reinforcing bar 5 is arranged and fixed along the longitudinal direction of the plate 3 . Further, a sub-reinforcing bar 7 is fixed at a predetermined angle with respect to the main reinforcing bar 5 . The deck plate 1 constructed in this way has a greater strength against bending in the longitudinal direction (A in the figure) than against bending in the lateral direction (B in the figure). That is, the deck plate 1 has different strength characteristics depending on its direction.

2A and 2B are plan views showing the arrangement of the deck plate 1, FIG. It is a figure which shows the state which carried out. As shown in FIG. 2( a ), large beams 11 are arranged between the four pillars 9 . A plurality of small beams 13 are fixed substantially parallel to the large beams 11 between the opposing large beams 11 .

When the small beams 13 are arranged in this manner, the distance between the small beams 13 (E in the figure) is shorter than the distance between the large beams 11 in the direction orthogonal to this (D in the figure). In this case, the deck plate 1 is arranged with the longitudinal direction of the deck plate 1 being the direction perpendicular to the small beams 13, which is the direction in which the distance between the beams is short. In FIG. 2(a), if the small beam 13 is not provided, the distance between the opposing large beams 11 (C or D in the figure), the direction with the shortest distance (for example, D in the figure) is the deck. The longitudinal direction of the plate 1 is assumed. By arranging in this way, it is advantageous to the strength of the structure and the like.

A plurality of shear connectors 17 are joined to the upper surface of the girders 11 . By using such a shear connector 17, the inertial force acting on the floor can be transmitted to the girder 11 even during an earthquake, and the floor slab can be securely fixed to the girder 11. In addition, since the upper flange of the steel beam made of H steel can be integrated with the floor slab, the floor slab contributes to the bending resistance of the steel beam as a composite beam combined with concrete, improving the rigidity as a whole. can be made

FIG. 3 shows a state in which concrete is placed above the deck plate 1 arranged in this way to construct a floor slab 15 . The floor slab 15 is integrated with the deck plate 1 and the girders 11 (shear connectors 17) and the like. Structural calculations are performed for the structural framework (pillars 9, large beams 11, small beams 13) and floor slab 15 in this state, and it is possible to confirm whether or not they have the desired bearing strength.

Here, the structural calculation support system 20 is not limited to include all of the above configurations, and may have only the configuration necessary to achieve the functions of the present invention. For example, a mobile terminal including a part of the configuration described above can also be applied. It should be noted that the computer in the present invention includes not only one physically independent device but also those in which each of the above components is distributed and arranged in a plurality of devices connected by a network.

(First embodiment)
Next, the operation of the structural calculation support system 20 will be described. FIG. 5 is a flow chart showing the operation of the structural calculation support system 20. As shown in FIG. The structural calculation support system 20 calculates the yield strength, deformation, etc. of a building at all times and during an earthquake, and can confirm whether or not the structure has the desired strength.

(Step 101)
As described above, the structural calculation support system 20 is executed by a computer with a program capable of calculating the stiffness of composite beams in which floor slabs and steel beams are integrated. First, the input unit 31 inputs floor load information to be calculated (floor load information input means).

In general, the load applied to the floor of the structure is set according to the type of building such as a warehouse where heavy objects are stored or the type of building in which a vehicle runs. The floor load information is information about the load capacity of the floor required for the target structure. Note that the floor load information corresponding to the type and size of the structure may be stored in the storage unit 25 in advance, and the floor load information may be input by selecting the type of structure using a pulldown or the like.

(Step 102)
Next, the control unit 23 uses the appropriate floor load information stored in the storage unit 25 to narrow down the types of beams applicable to the input floor load information (beam selection means). The storage unit 25 stores in advance a plurality of types of beams (model numbers and information such as section modulus, rigidity, strength, etc. of the beams of each model number). Information on the section modulus, rigidity, and strength of the beam may be calculated by the control unit 23 from the size of the beam.

The appropriate floor load information is associated with each type of beam, and the range of floor load information applicable to the beam is set. For example, there are only a limited number of beam types that can be successfully used in certain floor loading designs. If the rigidity of the beams is too low with respect to the floor load, the structure will not be established, and if the rigidity of the beams is too high, the design will be excessive and inappropriate. Therefore, for each beam, it is possible to set an appropriate range of floor load information designed for a structure using that beam.

More specifically, for each type of beam, the range of floor load information in which the beam can be used as a large beam and the range of floor load information in which the beam can be used as a small beam are set. In general, the required rigidity, etc., may differ between large beams and small beams. Therefore, even for the same beam type, the range of floor load information applicable to large beams and floor load information applicable to small beams is different from the range of For this reason, in the storage unit 25, appropriate floor load information that can be used as large girders and small girders is linked and stored for each type of beam, and the beam selection means uses the appropriate floor load information. , narrow down the types of beams as large beams and small beams applicable to the input floor load information.

(Steps 103, 104)
Next, the types of large beams and small beams to be used are selected from the types of beams selected by the beam selecting means (beam type selecting means). The user can select the beam model number or the like from, for example, a pull-down menu using the input unit 31 .

The selection of the small beams may be made directly from the types of beams selected by the beam selection means, or may be selected from among the types further narrowed down by the selected large beams. In this case, first, the type of girders to be used is selected from the types of beams narrowed down by the beam selection means. Next, the types of beams as small beams narrowed down by the beam selection means and having a smaller cross-section than the types of beams selected as large girders (beams with lower strength than the large girders) are narrowed down. , the type of beam used as the small beam can be selected from among these. By doing so, it is possible to further narrow the options for the small beams, making selection easier. As the small girders, it may be possible to select a type of beam that is larger than the size of the large girders (beams that are stronger than the large girders).

(Step 105)
Next, the control unit 23 narrows down applicable deck plate types from the beam types selected by the beam type selection means (deck plate selection means).

The storage unit 25 stores a plurality of deck plate types (model numbers and information on the section modulus, rigidity, strength, etc. of the deck plates of each model number) and appropriate beam type information linked to each deck plate type. Stored in advance.

Here, depending on the shape of the beam, the types of deck plates that can be properly applied are limited. For example, a thin deck plate with low rigidity cannot be applied to a beam of large size. Conversely, for smaller sized beams, there is no need to choose an overly thick deck plate. That is, there is a proper deck plate corresponding to each beam. For example, if a deck plate having a thickness 1.5 to 2 times the height of the beam can be applied, the types of beams that can be applied to each type of deck plate are limited. Thus, the appropriate beam type information is information on the type of beam (model number, size, etc.) that is appropriately applicable to each type of deck plate. The deck plate selection means uses the appropriate beam type information to narrow down applicable deck plate types from the types of girders selected by the beam type selection means.

(Step 106)
Next, the type of deck plate to be used is selected from the types of deck plates selected by the deck plate selection means (deck plate type selection means). The user can use the input unit 31 to select the model number of the deck plate from, for example, a pull-down menu.

(Step 107)
Next, the control unit 23 determines whether or not there is a small beam 13 for each area surrounded by the four pillars 9 . When the small beam 13 is present, the deck plate direction determination unit of the control unit 23 determines the direction perpendicular to the small beam 13 (in some cases, the parallel direction) as the longitudinal direction of the deck plate 1 . That is, when the small beams 13 are present, the interval between the small beams 13 is often shorter than the distance between the large beams 11 perpendicular to the small beams 13. and

On the other hand, when there is no small beam 13 , the deck plate direction determination unit of the control unit 23 determines the direction in which the distance between the large beams 11 is narrow as the longitudinal direction of the deck plate 1 . In addition, when the inter-beam distance is the same, the direction of the deck plate in the adjacent other region may be matched. In this way, the control unit 23 determines the direction of the deck plate 1 as the direction in which the distance between the beams is short, based on the shape of the space surrounded by the large beams 11 and the small beams 13 .

Thereafter, the control unit 23 acquires floor slab information corresponding to the selected deck plate 1 type and deck plate 1 direction from the storage unit 25 (floor slab information acquisition means).

The storage unit 25 stores floor slab information corresponding to the type of deck plate selected in advance. The floor slab information is information such as the rigidity of the floor slab when concrete having a thickness corresponding to the deck plate is cast. It should be noted that the floor slab information does not have to be listed in advance in the storage unit 25 for each type of deck plate. Floor slab information may be obtained.

(Step 108)
Next, the control unit 23 calculates stiffness information of a composite beam obtained by synthesizing the beam and the floor slab based on the type of beam and the floor slab information (rigidity information calculation means). The composite beam stiffness information calculation means calculates the stiffness of the composite beam using a known formula based on the type of beam and the floor slab information.

More specifically, the structural calculation of the beams and floor slabs is performed based on at least the strength characteristics of the large beams 11 and the small beams 13 read from the storage unit 25, the strength characteristics of the deck plate 1 in each direction, and the calculation conditions. I do. At this time, the strength characteristics of the deck plate 1 and the concrete placed on the deck plate 1 are also taken into consideration in the strength characteristics of the beam, and the strength of the composite beam on which the deck plate 1 is arranged is calculated. For example, in the conventional structural calculation, the strength calculation of the beam and the strength characteristics of the floor slab 15 are calculated separately. The strength of the beam is calculated as a structure with By doing so, more accurate intensity calculation can be performed.

The composite beam stiffness (composite beam basic stiffness information) corresponding to the shape information of the beam and the floor slab information may be calculated in advance and stored in the storage unit 25 . In this case, the stiffness information calculation means acquires the composite beam basic stiffness information (for example, stiffness per unit length) calculated in advance from the storage unit 25, and adds the length of the beam to the composite beam basic stiffness information. By doing so, the stiffness information of the composite beam may be calculated.

In addition to the stiffness information of the composite beam, the rigidity information calculation means may calculate at least one of the bending strength information of the composite beam, the shear strength information of the composite beam, or the lateral buckling strength information of the composite beam. A known calculation formula is used for these calculations.

Next, the control unit 23 calculates the shear strength required between the beam and the floor slab from the rigidity information of the composite beam. Further, the strength information of the shear connector that integrates the beam and the floor slab may be obtained from the storage unit 25, and the required number of shear connectors may be calculated from the rigidity information of the composite beam and the strength information of the shear connector. By doing so, it is possible to know the minimum number of shear connectors required, and it is possible to grasp the work time, cost, etc., including the welding work of the shear connectors.

(Steps 109, 110)
Next, the control unit 23 compares the stiffness information of the composite beam calculated by the stiffness information calculating means with the floor load information. The control unit 23 also controls the rigidity information of the composite beam, the bending resistance information of the composite beam, the shear strength information of the composite beam, or the lateral buckling resistance information of the composite beam, the number of shear connectors, the rigidity information of the composite beam, and the floor load information. Among the comparison results, etc., necessary items are output to the display unit 33 (stiffness information output means).

For example, as a comparison result between the rigidity information of the composite beam and the floor load information, the safety factor for the floor load information can be output. Furthermore, by linking unit price information to each member, it is possible to output the cost of the member to be used. Furthermore, calculations can be performed under multiple conditions, and the results can be displayed simultaneously for comparison. Needless to say, the result of each item can be stored in the storage unit 25 and transmitted to a printer or other terminal.

As described above, according to the first embodiment, the types of beams applicable to the floor load information are narrowed down by calculating backward from the necessary floor load information. Therefore, the beam type selecting means can select the beam type to be used from among the beam types selected by the beam selecting means. In this way, by omitting some of the unnecessary beam type options and reducing the number of beam options, it becomes easier to select beams, saves time and effort during input, and prevents wrong selections. can do. At this time, it is possible to perform calculations with a higher degree of freedom by making it possible to select the large beam and the small beam respectively.

Also, using the appropriate beam type information, applicable deck plate types can be narrowed down from the beam types selected by the beam type selection means, and the type of deck plate to be used can be selected from among these. In this way, by omitting some unnecessary deck plate type options and reducing the number of deck plate options, deck plate selection becomes easier, labor at the time of input is reduced, and erroneous selection is made. can be suppressed.

In addition, when performing structural calculations, in order to directly calculate the rigidity of the composite beam by adding the strength characteristics of the deck plate 1 and the strength characteristics of the concrete placed on the deck plate 1 to the strength characteristics of the beam, the large beam 11 and the small beam The intensity of each of the 13 can be calculated more accurately. In addition, since there is no need to separately calculate the stiffness of the composite beam, it is possible to save time and effort for calculation.

Further, since the arrangement direction of the deck plate 1 is automatically determined without the user inputting it into the system, it is possible to save the trouble of inputting. At this time, by making the side with the shorter beam interval the longitudinal direction of the deck plate 1, the direction of the deck plate 1 with high strength can be applied to the direction with weak strength of the structure, and the structure can be efficiently constructed. can improve the strength characteristics of

In addition, since the floor load information of the structure required according to the type and use of the structure and the calculated rigidity are compared, it is easy to determine whether the selected conditions are appropriate and whether the design is excessive. can grasp.

In addition, in order to calculate the number of shear connectors so that the floor slab can be fixed to the girders 11 with strength corresponding to the rigidity of the composite girders, the upper flanges of the steel beams must be efficiently integrated with the floor slabs. can be done.

(Second embodiment)
Next, a second embodiment will be described. FIG. 6 is a flow chart showing the operation of the structural calculation support system 20 according to the second embodiment. In addition, in the following description, redundant description of the configuration similar to that of the first embodiment will be omitted. The second embodiment is substantially the same as the first embodiment, except that the deck plates are sorted and selected first, and then the beams are sorted and selected.

(Step 201)
This is the same as step 101 described above.

(Step 202)
Next, the control unit 23 uses the appropriate floor load information stored in the storage unit 25 to narrow down the types of deck plates applicable to the input floor load information (deck plate selection means). The storage unit 25 stores in advance the types of a plurality of deck plates (model numbers and information such as section modulus, rigidity, strength, etc. of the deck plates of each model number).

The appropriate floor load information is associated with each type of deck plate, and the range of floor load information applicable to the deck plate is set. For example, there are only a limited number of deck plates that can be successfully used in certain floor loading designs. If the rigidity of the deck plate (floor slab) is too low with respect to the floor load, the structure will not be established, and if the rigidity of the deck plate (floor slab) is too high, the design will be excessive and inappropriate. Therefore, for each deck plate, it is possible to set an appropriate range of floor load information designed for a structure using that deck plate.

(Step 203)
Next, the type of deck plate to be used is selected from the types of deck plates selected by the deck plate selection means (deck plate type selection means). The user can use the input unit 31 to select the model number of the deck plate from, for example, a pull-down menu.

(Step 204)
Next, the control unit 23 narrows down applicable beam types from the deck plate types selected by the deck plate type selection means (beam selection means).

As described above, depending on the type of deck plate, the size of beams that can be appropriately applied is limited. For example, a small size beam cannot be applied to a thick and rigid deck plate. Conversely, there is no need to select oversized beams for thin, less rigid deck plates. That is, there is an appropriate beam corresponding to each deck plate. The appropriate deck plate type information is information on the type of deck plate (model number, size, etc.) that is appropriately applicable to each beam type.

(Step 205)
Next, a beam type to be used as a large beam is selected from the beam types selected by the beam selecting means (beam type selecting means). The user can select the beam model number or the like from, for example, a pull-down menu using the input unit 31 .

(Step 206)
Next, the control unit 23 narrows down the types of small beams applicable to the selected large beam. In the storage unit 25, appropriate small beam type information that can be used when used as a large beam is linked and stored in advance for each type of beam. Using the appropriate small beam type information in the storage unit, the types of small beams applicable to the beam selected as the large beam are narrowed down.

(Step 207)
Next, the type of beam to be used as the small beam is selected from the types of small beams selected by the beam selecting means (beam type selecting means). The user can select the beam model number or the like from, for example, a pull-down menu using the input unit 31 .

(Steps 208-211)
This is similar to steps 107-110 described above.

According to the second embodiment, effects similar to those of the first embodiment can be obtained. In this way, by calculating back from the required floor load information and narrowing down the types of deck plates applicable to the floor load information, some of the unnecessary deck plate type options can be omitted in the deck plate type selection means. By reducing the number of deck plate options, it becomes easier to select a deck plate.

(Third embodiment)
Next, a third embodiment will be described. FIG. 7 is a flow chart showing the operation of the structural calculation support system 20 according to the third embodiment. The third embodiment is substantially the same as the first and second embodiments, but differs in that the beams and the deck plates are selected based on the floor load information instead of one.

(Step 301)
This is the same as step 101 described above.

(Step 302)
Next, the control unit 23 uses the first appropriate floor load information stored in the storage unit 25 to narrow down the types of beams applicable to the input floor load information (beam selection means). As described above, the storage unit 25 stores a plurality of beam types and the first appropriate floor load information associated with each beam type. In the first appropriate floor load information, a range of floor load information applicable to each beam is set for each type of beam.

(Step 303)
Next, the control unit 23 uses the appropriate deck plate type information stored in the storage unit 25 to narrow down the applicable deck plate types for each beam type selected by the beam selection means. (First deck plate sorting means).

(Step 304)
Further, the control unit 23 uses the second appropriate floor load information stored in the storage unit 25 to narrow down the types of deck plates applicable to the input floor load information (second deck plate selection means ). As described above, the storage unit 25 stores a plurality of deck plate types and the second appropriate floor load information associated with each deck plate type. In the second appropriate floor load information, a range of floor load information applicable to each deck plate is set for each type of deck plate.

(Step 305)
Next, a combination of girders and deck plates is selected from among the types of beams selected by the beam selection means and the types of deck plates applicable to each type of beam (beam and deck plate type selection means ). The types of deck plates applicable to each type of beam are narrowed down to the types of deck plates commonly selected by the above-described first deck plate selecting means and second deck plate selecting means. For example, when the user selects a beam model number or the like from a pull-down menu using the input unit 31, the type of deck plate corresponding to the beam is displayed in a pull-down menu and can be selected.

(Steps 306, 307)
Steps 306,307 are similar to steps 206,207.

(Steps 308-311)
This is similar to steps 107-110 described above.

According to the third embodiment, effects similar to those of the first embodiment can be obtained. In this way, by narrowing down the deck plate selection based on both the type of beam and the floor load information, it becomes possible to select the type of deck plate more efficiently.
