  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a building structural margin display device according to an embodiment of the present invention.

  The building structural margin display device 10 according to the embodiment of the present invention calculates the structural margin of a building and displays it for each part of the building.

  As shown in FIG. 1, the building structure margin display device 10 includes a specification plan change condition input unit 12, an external force condition input unit 14, a storage unit 16, a data acquisition unit 18, a structure margin calculation unit 20, and a display unit. 22 is provided.

  The specification plan change condition input unit 12 inputs, as a condition for calculating the structural margin of a building, a specification to be adopted for each part among specifications that can be adopted in a plurality of parts constituting the building. That is, information representing the structure of the building and the type and number of each member used in the building based on the design specifications of the building is input. For example, specifications such as the structure of the roof, pillar, beam, wall, etc. of the building and the type and number of each member to be used are input.

  The external force condition input unit 14 inputs, for example, information on snow conditions, earthquake occurrence conditions, wind pressure conditions, and the like as conditions for calculating the structural margin considering external forces.

  The storage unit 16 includes information on specifications that can be adopted in a plurality of parts constituting the building (for example, specifications of the weight of the structural member for each part of the building, cross-sectional performance, allowable force, etc.), the cost of each member, and the like. Is stored as member information for each specification and member, and the stored member information is used to calculate the structural margin.

  The data acquisition unit 18 stores member information (specification information of each member and cost of each member described above) corresponding to the conditions input by the specification plan change condition input unit 12 and the external force condition input unit 14. And a predetermined structural reference value representing the member performance of the specification to be adopted, together with the conditions input by the specification plan change condition input unit 12 and the external force condition input unit 14, the structure margin calculation unit 20 Output to. The structure reference value is described as being stored in the storage unit 16 and read out, but may be input by the specification plan change condition input unit 12.

  The structure margin calculation unit 20 calculates the structure margin for each part of the building based on the member information output from the data acquisition unit 18 and the structure reference value. In this embodiment, the structural margin is calculated as the structural margin obtained by dividing the allowable value of the building by the vertical load or external force. In the present embodiment, when the value calculated as the structural margin is “1” or more, it is assumed that there is a margin in the building structure. However, a value obtained by reversing the denominator and the numerator is used as the structural margin. Also good. In this case, if it is “1” or less, there is a margin in the building structure.

  The display unit 22 displays the structure margin for each part calculated by the structure margin calculation unit 20 on a display or the like. At this time, the display unit 22 displays the structural margin for each part so that it can be determined whether or not a predetermined criterion is satisfied. For example, the structure margin for each part may be displayed for a part that does not satisfy the standard in advance by a predetermined display method indicating that the specification or member change is urged. In addition, the display that can determine whether or not a predetermined standard is satisfied may be displayed so that a quantitative determination (numerical value determination or the like) of whether or not the standard is satisfied can be performed.

  That is, the calculation result of the structural margin for each part of the building can be displayed on the display unit 22 only by changing the condition input by the specification plan change condition input unit 12 or the external force condition input unit 14, and the initial specification It is possible to explicitly verify the effect of the structural margin due to plan change or reform from the state. Accordingly, it is possible to verify the effect of the structural margin due to the change or addition of the building member, and it is possible to select an appropriate member.

  In addition, the storage unit 16 further stores, as a history, the structure margin for each part of the building calculated and displayed by the structure margin calculation unit 20. At this time, the structure margin calculation condition (information input by the specification plan change condition input unit 12 or the external force input unit 14) and the identification information for identifying the building are stored in association with each other. As a result, when the structural margin is calculated by remodeling or revision of the Building Standard Law, the structural margin can be calculated using the history.

  Here, an example of a specific configuration of the building structural margin display device 10 according to the embodiment of the present invention will be described.

  FIG. 2 is a block diagram showing a specific configuration example of the building structural margin display device 10 according to the embodiment of the present invention.

  The building structural margin display device 10 includes a personal computer (PC) 30. The PC 30 includes a CPU 32, a ROM 34, a RAM 36, and an input / output port 38. These are connected to each other via various buses such as an address bus, a data bus, and a control bus. The input / output port 38 includes a display 40, a mouse 42, a keyboard 44, a hard disk (HD) 46, and a disk for reading information from various disks (for example, CD-ROM, DVD, etc.) 48 as various input / output devices. Each drive 50 is connected.

  A network 52 is connected to the input / output port 38, and information can be exchanged with various devices connected to the network 52. In the present embodiment, a data server 56 to which a database (DB) 54 is connected is connected to the network 52, and information can be exchanged with the DB 54.

  In the DB 54, information on specifications that can be adopted in a plurality of parts constituting the building (for example, specifications such as weight of a structural member for each part of the building, cross-sectional performance and allowable force), information on the cost of each part Is previously stored as member information for each part. Information storage in the DB 54 may be registered by the PC 30 or the data server 56, or may be registered by another device connected to the network 52.

  The DB 54 also stores information about external forces. As the information related to the external force, for example, information related to external force conditions such as snow, earthquake, wind pressure, etc. is stored, and based on the stored information, the structural margin for the external force can be calculated.

  Furthermore, in the DB 54, calculation conditions for calculating the structural margin in the initial specification state, calculation results of the structural margin, calculation results of the structural margin at the time of plan change or remodeling, and calculations for examining the effects of earthquakes, etc. A history such as the calculation result of the structure margin is stored. At this time, the calculation conditions at the time of calculating the structural margin and the identification information for identifying the building are stored correspondingly. In addition, the storage of information in the DB 54 in this case may be registered by the PC 30 or the data server 56, or may be registered by another device connected to the network 52.

  The display 40 functions as the display unit 22 described above, the PC 30 functions as the data acquisition unit 18 and the structure margin calculation unit 20 described above, and the mouse 42 and the keyboard 44 include the specification plan change condition input unit 12 and the external force described above. It functions as the condition input unit 14, and the data server 56 and the DB 54 function as the storage unit 16 described above. In the present embodiment, the DB 54 connected to the data server 56 stores information on specifications of a plurality of types of members used in the building (for example, specifications such as weight, cross-sectional performance and allowable force), and cost of each member. The information of the DB 54 may be stored in the HDD 46 built in the personal computer 30, an external hard disk, or the like.

  A structural margin simulation program for simulating the structural margin of a building, which will be described later, is installed in the HDD 46 of the PC 30. There are several methods for installing the structural margin simulation program of the present embodiment on the PC 30. For example, the structural margin simulation program is stored in a CD-ROM or DVD together with the setup program, and the disk A structure margin simulation program may be installed in the HDD 46 by setting a disk in the drive 50 and executing a setup program for the CPU 32, or connected to the PC 30 via a public telephone line or the network 52. The structural margin simulation program may be installed in the HDD 46 by communicating with other information processing devices.

  Subsequently, specific information stored in the DB 54 that stores information such as member information used in the structural margin simulation program and an example of a method of using the information will be described. FIG. 3A is a diagram illustrating an example of information stored in advance in the DB 54.

  In the present embodiment, a case where a unit house is assumed will be described as an example, but the present invention is not limited to a unit house. In the present embodiment, each unit constituting the building is described as having a ramen structure. However, the present invention is not limited to this, and other structures may be applied. For example, other structures include trusses in which the joint portions of the members are pin-joined, a wall-type structure in which the members are regarded as surfaces rather than lines, and an art structure that converts a bending moment into a compressive force.

  As shown in FIG. 3 (A), the DB 54 stores in advance information on members used in the ramen structure, and specifications of member performance (weight, cross-sectional performance, allowable force, etc.) for each part. ) In advance. In addition, cost information for each part is also stored in advance in order to simulate cost fluctuations due to member changes and the like.

  Various members used in the above-mentioned ramen structure are stored in the DB 54 as information contents according to a predetermined rule. For example, when designating the north, south, west, and east side ramen structures of the unit, in the example shown in FIG. The east side is specified as “AB01CC”.

  In this embodiment, the rule shown in FIG. 3C is applied to the symbol rule for each face of the unit. In the case of FIG. 3C, one digit from the left represents the beam cross-section variation, two digits from the left represent the column cross-section variation, three to four digits from the left represent the span variation, and five to six digits from the left. Represents a variation of ramen shape.

  As an example, FIG. 3D shows an example in which the members of the ramen structure of each unit constituting the building are designated. FIG. 3D shows a case where a building is configured with seven units having unit IDs (U · UD :) of 1 to 7.

  Further, as described above, the DB 54 stores information related to the external force condition, but as the information related to the external force, in order to calculate the structural margin corresponding to the area where the building for which the structural margin is to be calculated is located. These conditions are stored. For example, a predetermined coefficient or the like corresponding to the amount of snow in each region, the number of earthquake occurrences or seismic intensity in each region, the wind pressure in each region, etc. is stored as information for calculating the structural margin for external force. By setting the region, etc., it is possible to calculate the structural margin considering external force by multiplying the structural margin of the entire building by the coefficient stored corresponding to the region.

  Next, a process flow when the structural margin simulation program is executed on the PC 30 will be described.

  In the present embodiment, the structure margin degree program can display the structure margin degree in the initial specification state and simulate the structure margin degree due to specification change, reform, and the like.

  First, the case where the structural margin in the initial specification state is displayed will be described. FIG. 4 is a flowchart showing the flow of processing when a structural margin simulation program (display of initial specification state) is executed by the PC 30 of the building structural margin display device 10 according to the embodiment of the present invention.

  In Step 100, a predetermined unit setting screen for setting the units constituting the building based on the initial design specifications is displayed on the display 40, and the process proceeds to Step 102.

  In step 102, it is determined by the CPU 32 whether or not the unit setting is input by the keyboard 44 or the mouse 42, and the process waits until the determination is affirmed, and the process proceeds to step 104. That is, settings relating to units such as the number of units constituting the building and the arrangement of units with respect to the building are performed. In the present embodiment, at the time of unit setting, house identification information for identifying the house is also input at the same time. As a result, when a plan change or the like to be described later is performed, it is possible to perform a simulation of the structure margin at the time of the plan change to be described later based on the residence identification information. When the building has a structure other than the unit house, settings relating to the structure of the building to be applied are performed in this step.

  In step 104, a predetermined ramen setting screen for setting the ramen structure of each unit is displayed on the display 40, and the process proceeds to step 106. The ramen setting screen is a screen for setting the type of members used in the ramen structure, the number of members, and the like, and the setting is set according to the rules of FIG. 3C, for example.

  In step 106, it is determined by the CPU 32 whether or not the input of the member setting of the ramen structure for each unit has been performed by the keyboard 44, the mouse 42, etc.

  In step 108, a predetermined external force setting screen for setting conditions relating to external forces such as snow, earthquake, and wind pressure is displayed on the display 40, and the process proceeds to step 110.

  In step 110, it is determined by the CPU 32 whether or not the input of the external force setting has been performed by the keyboard 44 or the mouse 42. The CPU 32 waits until the determination is affirmed and proceeds to step 112.

  In step 112, information about member performance of the set rigid frame structure (species such as member weight, cross-sectional performance, allowable force) is acquired from the DB 54 via the network 52, and the process proceeds to step 114.

  In step 114, information corresponding to the set external force condition is acquired from the DB 54 via the network 52, and the process proceeds to step 116.

  In step 116, the structural margin is calculated by the operation of the CPU 32, and the process proceeds to step 118. That is, the structural margin for each predetermined part of the building is calculated using each set condition and information on each member acquired from the DB 54, and external force (snow condition, seismic force, wind pressure, etc.) The structural margin for each is calculated.

  In step 118, the calculated structural margin is displayed on the display 40 for each part, and the series of processes is terminated. In the present embodiment, when the calculated structural margin is displayed on the display 40, the calculated structural margin of each part is a part where the structural margin is insufficient (part where the structural margin is less than 1). ) Is displayed so that it can be determined that the structural margin is insufficient by blinking or displaying in a display color different from other display colors. In other words, the structural margin is displayed by a display method that indicates prompting the member to change the part where the structural margin is insufficient.

  Next, a case where a structural margin simulation is performed when a plan change is performed will be described. FIG. 5 is a flowchart showing the flow of processing when the structural margin simulation program (plan change) is executed by the PC 30 of the building structural margin display apparatus 10 according to the embodiment of the present invention.

  In step 200, a plan change condition setting screen for inputting a change in structure, a member change used in the ramen structure, and the like is displayed on the display 40, and the process proceeds to step 202.

  In step 202, it is determined by the CPU 32 whether or not the condition change input has been performed by the keyboard 44 or the mouse 42, and the process waits until the determination is affirmed and the process proceeds to step 204. In addition, when entering the condition change, by inputting the residence identification information corresponding to the plan to be changed, the calculation conditions used in the initial specification state and the calculated structural margin of each part are read, and the condition change input I do. Further, the calculation conditions and the calculated structural margin used in the initial specification state are temporarily stored in the RAM 36 or the like and used in the steps described later.

  In step 204, information about the changed member and external force condition is acquired from the DB 54 via the network 52, and the process proceeds to step 206. That is, information corresponding to the input condition change is read from the DB 54.

  In step 206, the structure margin after the change is calculated by the calculation of the CPU 32, and the process proceeds to step 208. That is, the structural margin for each part is calculated using the calculation conditions used in the initial specification state, the calculation conditions changed and input, and information (specs of each member, etc.) corresponding to the condition change acquired from the DB 54. Calculated.

  In step 208, the structural margin before and after the change is displayed on the display 40, and the process proceeds to step 210. That is, the structural margin calculated in the initial specification state and the structural margin for each part calculated by changing the conditions are displayed on the display 40. Further, in the present embodiment, when the calculated structural margin is displayed on the display 40, among the calculated structural margins of each portion, the portion where the structural margin is insufficient (the structural margin is more than 1). The small part) is displayed so that it can be determined that the structural margin is insufficient by blinking or displaying in a display color different from other display colors. In other words, the structural margin is displayed by a display method that indicates prompting the member to change the part where the structural margin is insufficient.

  In step 210, it is determined whether to display the cost fluctuation. In this determination, it is determined whether or not an operation representing a cost fluctuation display instruction has been performed by the keyboard 44 or the mouse 42. If the determination is affirmative, the process proceeds to step 212. If the determination is negative, the operation is continued. A series of processing ends.

  In step 212, information regarding the cost of each member is acquired from the DB 54 via the network 52, and the process proceeds to step 214.

  In step 214, the cost fluctuation is calculated by the calculation of the CPU 32 using the acquired cost information, and the process proceeds to step 216.

  In step 216, the calculation result of the cost fluctuation is displayed on the display 40, and the series of processing ends. That is, since the cost fluctuation is also displayed, it is possible to examine the member change considering the cost.

  In the present embodiment, the calculation of the structure margin in the initial specification state and the calculation of the structure margin in the case of the plan change have been described as separate processes (FIGS. 4 and 5), but this is not limitative. Alternatively, a plurality of plans may be set as a condition, and the structure margin for each part may be calculated for each plan at the same time so that the process can be displayed on the display 40.

  Next, an example of displaying the calculation result of the structural margin calculated by performing the above-described structural margin simulation will be described.

  For example, an example will be described in which the calculation result of the structural margin of a building including a Western-style room, a hall, an entrance, a living room, and a dining / kitchen shown in FIG. 6 is displayed.

  FIG. 7 is a diagram showing an outline of the simulation when displaying the structure margin, and FIGS. 8 and 9 are examples showing the results of calculating the structure margin for the initial state and each pattern.

  By executing the structural margin simulation program described above, the calculation result of the structural margin is displayed on the display 40 for each part of the vertical load (roof, outer wall, floor, and loading load) as shown in FIG. In addition, the calculation result of the structural margin with respect to the external force (snow accumulation condition, seismic force, and wind pressure) is displayed on the display 40. In FIG. 8, the result shown by the solid line indicates the calculation result of the structural margin in the initial specification state.

  Here, in the case of the initial specification state indicated by the solid line in FIG. 8, the structural margin is 2.0 or more in each part, the structural margin is large, and there is room for cost reduction. Therefore, the specifications of the members in each part are changed, and the structural margin is simulated.

  As the contents of the change, the pattern 1 in FIG. 7 changes the specifications of the hatched part (“other accessories”) with respect to the initial state, and the pattern 2 shows the hatched part with respect to the initial state ( The specifications of “Spring material”, “Other accessories”, “Outer plate”, “Substrate + finish material”, and “Loading load”) are changed, and pattern 3 is hatched with respect to the initial state (“ An example in which the specifications of “spreading material”, “other accessories”, “outer plate”, “base + finishing material”, and “loading load”) are changed is shown as an example. As a result of the plan change, as shown in FIG. 8, the calculation results of the structural margins of patterns 1 to 3 are displayed on the display 40. The long dotted line in FIG. 8 indicates the calculation result of the structural margin of pattern 1, the dotted line indicates the calculation result of the structural margin of pattern 2, and the alternate long and short dash line indicates the calculation result of the structural margin of pattern 3.

  As shown in FIG. 8, the structural margin decreases in the order of the initial state, patterns 1, 2, and 3, and in pattern 3, the structural margin of the seismic force becomes 1 or less and the structural margin is insufficient. Here, a display such as blinking or changing the display color is performed for a portion where the structural margin is less than 1, and the user can be notified that the structure is changed to an appropriate member. The user confirms the display, changes the structure as in the pattern 3 ′ with respect to the pattern 3, and performs the simulation of the structure margin. As a result, for example, as shown in FIG. 9, the calculation result of the structural margin for each part indicated by the dotted line is displayed. That is, by changing the plan from the alternate long and short dash line (pattern 3) to the dotted line (pattern 3 ′), the structural margin becomes “1” or more in all the parts, and the necessary and sufficient structural margin can be obtained. An excessive margin can be prevented. The portion indicated by hatching in FIG. 9 indicates the occurrence of the structure margin when the structure is changed. Note that “●” in FIG. 9 indicates the calculation result of the structural margin in the initial state at the time of the pattern 3 ′.

  Next, the calculation result of the structural margin when the living room of the building including the Western-style room, hall, entrance, living room, dining room and kitchen shown in FIG. 6 is changed to the inner garage as shown in FIG. The display will be described. The outline of the simulation in the case of performing the reform to change to the inner garage is the pattern 4 shown in FIG. Further, a case where the reform to be changed to the inner garage and the specification change of the above-described pattern 2 are performed are shown as a pattern 2 '.

  FIG. 12 shows, as a dotted line, a display example of the calculation result of the structure margin when the reform to the inner garage is performed with respect to the initial specification state, and the specifications of the reform to be changed to the inner garage and the pattern 2 are changed. A display example of the calculation result of the structural margin in this case is shown as a one-dot chain line.

  When remodeling and pattern 2 are changed to the inner garage, the strength of the building is reduced by cutting the floor beams of the unit, and the structural margin is less than “1”. When remodeling is performed to change to the inner garage with respect to the specification state, even if the building proof strength is reduced by cutting the floor beam of the unit, the structural margin of “1” or more can be secured. I understand. That is, by examining these simulations, the structural margin at the time of reform can be examined.

  Note that the actual load after the lapse of a predetermined period may be measured to simulate the structural margin. In this case, the actual load measurement is performed by executing the structural margin simulation program and performing condition change input (step 202) reflecting the measurement result of the actual load on the portion where the actual load is changing. Since the structural margin considering the result can be calculated, it is possible to study seismic reinforcement work and renovation. When inputting the actual load measurement result, the actual load measurement result is input instead of at least a part of the specification input in at least one part, instead of inputting the measurement result of all parts. You may do it.

  Then, by storing the simulation results of these structural margins as a history in the DB 54, it can be used for the subsequent examination of seismic reinforcement work or renovation. For example, as an example of the history stored in the DB 54, a history as shown in FIG. In the example of FIG. 13, each time of calculation (initial specification state), construction, year after construction, year △ (when pattern 1 specification is changed), year □ (result when an earthquake occurs), year ◇ The example which memorize | stores the simulation result of a structure margin as a log | history is shown.

  On the other hand, it is also possible to perform a simulation of the structural margin associated with the revision of the Building Standard Law. For example, in the above-described structural margin simulation program, by making it possible to change the standard on the plan change condition setting screen in step 200, it is possible to calculate the structural margin due to revision of the Building Standards Act, etc. For example, the calculation result shown in FIG. 14 can be displayed on the display 40.

  In the example of FIG. 14, the calculation result of the structural margin when the building standard law is revised for each of the initial specification state indicated by the solid line, the pattern 1 indicated by the long dotted line, and the pattern 2 indicated by the dotted line is shown. The part shown by the thick line in FIG. 14 shows the part where the fluctuation of the structural margin occurred due to the revision of the Building Standard Law. In this way, even when the Building Standards Law is revised, the structural margin can be simulated, and the result can be explicitly displayed.

  Next, an example of displaying the cost fluctuation due to the change of the member specification or the reform will be described. As an example, an example will be described in which a cost change due to a plan change is displayed in a case where a building is configured with 7 units of FIG.

  FIG. 15A is a diagram illustrating an example of a member used in the unit IDs 1 to 7, and FIG. 15B is an example of a member used in the unit IDs 1 to 7 after the member is changed due to plan change or reform. FIG. That is, at the time of execution of the structural margin simulation program (initial specification state), each unit of FIG. 15A and each member of each unit are set and input. In the structural margin simulation program, the change contents of FIG. The settings are input. A portion indicated by hatching in FIG. 15B is a portion in which the member is changed with respect to FIG.

  In this case, since the cost variation due to changing the cross-sectional type of the beam and the cost increase variation due to changing the cross-sectional type of the column occur, the cost of each member is read from the DB 54, and the variation for each unit is calculated. It calculates and displays on the display 40 (for example, FIG. 16 (A)-(C)).

  FIG. 16A is an example of displaying the cost variation due to the change in the cross-sectional type of the beam. In this case, the cross-sectional type of the column changed for each unit, the cost variation accompanying the change, the subtotal, and An example of calculating and displaying the total beam cost increase is shown.

  FIG. 16B is an example of displaying the cost variation due to the change in the column section type. In this case, the beam section type changed for each unit, the cost variation associated with the change, and An example of calculating and displaying the total beam cost increase is shown.

  FIG. 16C shows an example of displaying the results of calculating the total cost of the beam cost increase, the column cost increase, and the total.

  In addition, although each said embodiment showed the various display examples displayed on the display 40, the arrangement | sequence and display method of the information to display are not restricted to this, You may make it set suitably. .
