Description

The present invention relates to a structure calculation support system and a program for calculating a structure of a building.

Conventionally, at the time of designing a building, structural calculation (strength examination) at all times or at the time of earthquake is performed to calculate the proof stress and deformation of each part. When performing such calculation, a structural calculation support system (program) is used. Structural calculation is performed by inputting necessary data to the system.

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

On the other hand, in a structure, a deck plate that doubles as a formwork of a concrete floor slab and a structure may be used. In the conventional design support system, in the structural calculation of a structure using such a deck plate, instead of inputting the rigidity value of the steel beam of the structure, the steel beam and concrete are integrated in advance. The rigidity value of the composite beam is separately calculated (for example, Patent Document 2), and the structural value of the structure is calculated by inputting the rigidity value.

JP, 2002-230045, A JP, 2012-12788, A

In such a conventional structural design support system, it is necessary to input a lot of information used for calculation. Therefore, it is required to save the effort of inputting as much as possible. In addition, a separate calculation process for obtaining the rigidity of the composite beam is required, which is troublesome.

In addition, in the conventional design support system, in the frame calculation of the structure, a consistent structural calculation is performed using only the input data of the steel beam cross section, and it is examined whether lateral buckling failure of the beam will occur separately I had judged the validity of the calculation of the product. However, the study of lateral buckling failure of this beam is troublesome because it is performed separately from the frame calculation of the structure.

The present invention has been made in view of such a problem, and provides a structural calculation support system and a program that reduce the time and effort of inputting information and can reduce the time and cost of separate calculations. The purpose is to do.

In order to achieve the above-mentioned object, the first invention is a program capable of calculating the rigidity of a composite beam in which a floor slab and a steel beam are integrated by a computer, and the computer inputs the beam shape information. Beam information input means, deck plate type selection means for selecting the type of deck plate, floor slab information acquisition means for calculating or acquiring floor slab information corresponding to the selected type of deck plate from the storage unit, and the beam Shape information, based on the floor slab information, rigidity information calculation means for calculating the rigidity information of the composite beam that combines the beam and the floor slab, and rigidity information output means for outputting the rigidity information of the composite beam, It is a program characterized by making it function as.

The rigidity information calculation means corresponds to the beam shape information and the floor slab information, acquires composite beam basic rigidity information calculated in advance from a storage unit, and calculates the composite beam basic rigidity information based on the composite beam basic rigidity information. It is desirable to calculate stiffness information.

Even though the shape information of a plurality of types of beams is stored in the storage unit, the beam information input means can select and input from the shape information of the beams stored in the storage unit. Good.

In the storage unit, appropriate beam type information corresponding to the type of the deck plate is stored in association with each other, and the beam shape information input by the beam information input means and the appropriate beam type information are stored. And a deck plate type selection means for selecting a deck plate type that matches the shape information of the beam, and the deck plate type selection means is one of the deck plate types selected by the deck plate type selection means. Therefore, the deck plate type may be selectable.

In addition to the rigidity information of the composite beam, the rigidity information calculation means may calculate at least one of bending strength information of the composite beam, shear strength information of the composite beam, and lateral buckling strength information of the composite beam.

The beam information input means inputs the arrangement information of both girders and girders, and the floor slab information acquisition means determines the direction of the deck plate from the shape of the space surrounded by the girders and girders, You may acquire the said floor slab information corresponding to the said direction.

The required rigidity information of the structure necessary for the structure according to the type or use of the structure is acquired, and the rigidity information output means displays the comparison result between the calculated rigidity information of the composite beam and the requested rigidity information. Output may be possible.

It is possible to obtain strength information of a shear connector that integrates the beam and the floor slab, and calculate the required number of shear connectors from the rigidity information of the composite beam and the strength information of the shear connector. Good.

According to the first aspect of the present invention, when the strength characteristics of the beam are calculated, the strength characteristics of the composite beam are calculated by inputting the types of the beam and the deck plate so that the strength characteristics of the concrete placed on the deck plate are taken into consideration. It can be calculated. Therefore, no separate calculation or the like is necessary, and an appropriate structural calculation can be performed.

In addition, as a method of calculating the stiffness information of composite beams, instead of calculating the stiffness of composite beams from the beam shape information and floor slab information each time, the composite beam corresponding to the beam shape information and floor slab information is calculated. It is also possible to store the basic rigidity information in advance in the storage unit and to easily calculate the composite beam rigidity information by multiplying the composite beam basic rigidity information by parameters such as the width and length of the beam.

Further, when the beam shape information is input, the beam information can be easily input by selecting from a plurality of beam shape information stored in the storage unit in advance.

In addition, by preliminarily associating appropriate beam type information corresponding to the type of deck plate, the deck plate type that matches the input beam is selected, and the deck plate type can be selected from among them. It becomes easy to select a desired deck plate from a large number of deck plate types.

Further, in addition to the rigidity information of the composite beam, more accurate structural calculation can be performed once by calculating at least one of bending strength information of the composite beam, shear strength information of the composite beam, and lateral buckling strength information of the composite beam. Can be done.

Also, by determining the direction of the deck plate from the shape of the space surrounded by the girders and crossbeams, it is not necessary to input the direction of the deck plate, and it is possible to save the trouble of inputting the direction of the deck plate. .. Further, if the orientation of the deck plate is determined, the input of calculation conditions such as the floor load transmission direction can be omitted.

In addition, by comparing the required rigidity of the structure required for the structure according to the type or application of the structure with the calculated rigidity information of the composite beam, the calculated rigidity of the structure is It is possible to easily judge whether it is the ratio or whether the selection of the beam or the like is appropriate.

Further, by presetting the strength information of the shear connector that integrates the beam and the floor slab, it is possible to grasp the required number of shear connectors required for the rigidity of the composite beam.

ADVANTAGE OF THE INVENTION According to this invention, the structural calculation support system and program which can reduce the effort of inputting information and can reduce the effort of separate calculation can be provided.

The perspective view which shows the deck plate 1. (A) is a plan view showing the arrangement of columns 9, girders 11 and beamlets 13, and (b) is a plan view showing a state in which the deck plate 1 is arranged. The side view showing the state where floor slab 15 was built. The figure which shows the hardware constitutions of the structural calculation support system 20. The flowchart which shows the process of the structural calculation support system 20.

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

The plate 3 is, for example, a steel plate having a fine corrugated shape. The main reinforcing bars 5 are arranged and fixed along the longitudinal direction of the plate 3. Further, the sub-rebar 7 is fixed to the main rebar 5 at a predetermined angle. The deck plate 1 configured in this manner has a greater strength against bending in the longitudinal direction (A in the drawing) than bending against the shorter side (B in the drawing). That is, the deck plate 1 has different strength characteristics depending on its direction.

FIG. 2 is a plan view showing the arrangement of the deck plate 1, FIG. 2(a) is a view showing the arrangement of the pillar 9, the girder 11 and the girder 13, and FIG. 2(b) is the arrangement of the deck plate 1. It is a figure which shows the state which was done. As shown in FIG. 2A, a girder 11 is arranged between the four columns 9. Further, between the large beams 11 facing each other, a plurality of small beams 13 are fixed substantially parallel to the large beams 11.

In this way, when the crossbeams 13 are arranged, the distance between the crossbeams 13 (E in the drawing) is shorter than the distance between the crossbeams 11 in the direction orthogonal to this (D in the drawing). In this case, the deck plate 1 is arranged with the direction perpendicular to the beam 13, which is the direction in which the intervals between the beams are short, as the longitudinal direction of the deck plate 1. In addition, in FIG. 2A, when the cross beam 13 is not provided, the direction in which the distance is short (for example, D in the drawing) among the intervals (C or D in the drawing) between the facing large beams 11 is set to the deck. It is the longitudinal direction of the plate 1. By arranging in this way, it becomes advantageous in the yield strength of the structure.

A plurality of shear connectors 17 are joined to the upper surface of the girder 11. By using such a shear connector 17, an inertial force acting on the floor can be transmitted to the girder 11 even during an earthquake, and the floor slab can be reliably fixed to the girder 11. Further, 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 and improves the overall rigidity as a composite beam that is combined with concrete. Can be made

FIG. 3 shows a state in which the floor slab 15 is constructed by placing concrete on the deck plate 1 with the deck plate 1 thus arranged. The floor slab 15 is integrated with the deck plate 1 and the girder 11 (shear connector 17) and the like. Structural calculation is performed on the structural frame (column 9, girder 11, beam 13) and floor slab 15 in this state, and it is possible to confirm whether or not it has a desired yield strength.

Realizes the processing performed by.

The ROM is a non-volatile memory, and permanently holds a computer boot program, programs such as BIOS, data, and the like. The RAM is a volatile memory, and temporarily stores programs, data, and the like loaded from the storage unit 25, the ROM, the recording medium, and the like, and includes a work area used by the control unit 23 to perform various processes.

The storage unit 25 is an HDD (hard disk drive) or SSD (solid state drive), and stores a program executed by the control unit 23, data necessary for executing the program, an OS (operating system), and the like. As for the programs, a control program corresponding to the OS (operating system) and an application program corresponding to the processing described later are stored. Each of these program codes is read by the control unit 23 as needed, transferred to the RAM, read by the CPU, and executed as various means.

The storage unit 25 stores various data used in the present invention. For example, the strength characteristics of the pillar 9, the girder 11 and the girder 13, the type of the deck plate, the strength characteristics in the longitudinal direction and the lateral direction of the deck plate 1, the floor slab information corresponding to the type of the deck plate, the beam The composite beam basic rigidity information corresponding to the shape information and floor slab information, the appropriate beam type information corresponding to the type of deck plate, the required rigidity information of the structure, the shear connector strength information, etc. are stored.

The bus 37 is a path that mediates exchange of control signals, data signals, etc. between the respective devices. Here, the structural calculation support system 20 is not limited to the one including all the above-mentioned configurations, and may have only the configuration necessary for achieving the functions of the present invention. For example, a mobile terminal or the like including some of the configurations described above is also applicable.

Next, the operation of the structural calculation support system 20 will be described. FIG. 5 is a flowchart showing the operation of the structural calculation support system 20. The structural calculation support system 20 calculates the proof stress, deformation, etc. of the building at all times and at the time of an earthquake, and can confirm whether the structure has a desired strength by calculation.

(Step 101)
As described above, the structural calculation support system 20 is executed by a computer by a program capable of calculating the rigidity of the composite beam in which the floor slab and the steel beam are integrated. First, the input unit 31 inputs the type (or application) of the structure to be calculated and the arrangement information and shape information of the pillar 9 and the beam (both the large beam 11 and the small beam 13) (beam information input means). ..

The type of structure is, for example, a type of building such as a warehouse in which heavy goods are stored, a type of building in which a vehicle travels, and can be selected by pulling down, for example. It should be noted that the storage unit 25 stores required rigidity information necessary for the structure according to the type of each structure. For example, in the case of a building in which a vehicle or the like runs, the required rigidity required is set higher than that of a residential building.

The beam shape information is input for each of the girder 11 and the girder 13. The beam shape information is information on the cross-sectional shape and length of the beam. The control unit 23 can calculate the cross-sectional modulus, rigidity, and strength of the beam based on the beam shape information. The beam shape information may be the model number or size of the member used, or the strength or the like according to the beam shape may be directly input. Further, even if the shape information of a plurality of types of beams is stored in the storage unit 25 in advance and the shape information of the beam is selected from the list of the shape information of the beams stored in the storage unit 25 and input. Good.

(Steps 102 and 103)
Next, the type of deck plate is selected by the input unit 31 (deck plate type selection means). The storage unit 25 stores the type of deck plate. The type of deck plate may be, for example, a model number, or may be shape parameters such as length and thickness. The user can select the type from the model number of the deck plate by pulling down, for example.

The storage unit 25 stores in advance floor slab information according to the selected type of deck plate. 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 placed.

Here, depending on the shape of the beam, the type of deck plate that can be applied appropriately is limited. For example, it is not possible to apply a thin and low-rigidity deck plate to a large-sized beam. Conversely, for smaller beams, it is not necessary to choose an overly thick deck plate. That is, there is a proper deck plate corresponding to each beam.

In the storage unit 25, appropriate beam type information corresponding to the type of deck plate is stored in advance in association with each other. When the beam shape information is input, the control unit 23 compares the beam shape information input by the beam information input unit with the appropriate beam type information of each deck plate, and the deck that matches the beam shape information. Select the plate type (deck plate type selection means). In the deck plate type selecting means, the deck plate type can be selected from the deck plate types selected by the deck plate type selecting means. As described above, by omitting some unnecessary deck plate options and reducing the number of deck plate options, the selection of the deck plate is facilitated, and the labor at the time of input is reduced.

(Step 104)
Next, the control unit 23 determines whether or not there is the beam 13 in each region surrounded by the four columns 9. When the cross beam 13 is present, the deck plate direction determining unit of the control unit 23 determines the direction perpendicular to the cross beam 13 as the longitudinal direction of the deck plate 1. That is, when the small beams 13 are provided, the distance between the small beams 13 is shorter than the distance between the large beams 11 orthogonal to the small beams 13. Therefore, the direction in which the distance between the small beams is short is the longitudinal direction of the deck plate 1.

On the other hand, when there is no cross beam 13, the deck plate direction determination unit of the control unit 23 determines that the direction in which the intervals between the cross beams 11 are narrow is the longitudinal direction of the deck plate 1. When the distance between the beams is the same, it may be aligned with the direction of the deck plate in another adjacent area. In this way, the control unit 23 determines, as the direction of the deck plate 1, the direction in which the distance between the beams is short from the shape of the space surrounded by the large beam 11 and the small beam 13.

After that, the control unit 23 acquires the floor slab information corresponding to the selected type of the deck plate 1 and the direction of the deck plate 1 from the storage unit 25 (floor slab information acquisition unit). The floor slab information does not have to be listed in advance in the storage unit 25 for each type of deck plate, and the rigidity of the floor slab is calculated each time according to the selected type of deck plate. Floor slab information may be acquired.

(Step 105)
Next, the control unit 23 calculates the rigidity information of the composite beam in which the beam and the floor slab are combined, based on the beam shape information and the floor slab information (rigidity information calculation means). The composite beam rigidity information calculating means calculates the rigidity of the composite beam by a known calculation formula based on the beam shape information and the floor slab information.

More specifically, based on at least the strength characteristics of the large beam 11 and the small beam 13 read from the storage unit 25 and the strength characteristics in each direction of the deck plate 1 and the calculation conditions, the structural calculation of the beam and the floor slab is performed. I do. At this time, the strength characteristics of the deck plate 1 and the concrete strength cast on the deck plate 1 are also added to the strength characteristics of the beam to calculate the strength of the composite beam on which the deck plate 1 is arranged. For example, in the conventional structural calculation, the beam strength calculation and the strength characteristic of the floor slab 15 are calculated separately, but in the present embodiment, the floor slab 15 is integrally constructed on the beam by a stud connector or the like. The strength of the beam is calculated as a structure. By doing so, more accurate intensity calculation can be performed.

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

In addition to the rigidity information of the composite beam, the rigidity information calculating means may calculate at least one of bending strength information of the composite beam, shear strength information of the composite beam, and lateral buckling strength information of the composite beam. Known calculation formulas are used for these calculations.

(Step 106)
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 is acquired from the storage unit 25, and the required number of shear connectors is 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 required number of shear connectors, and it is possible to ascertain the working time and cost including the welding work of the shear connectors.

(Steps 107, 108)
Next, the control unit 23 obtains the required rigidity information of the structure required for the structure according to the type or use of the structure from the storage unit 25, and the rigidity information and the request of the composite beam calculated in step 105. Compare with stiffness information. Further, the control unit 23 controls the composite beam rigidity information, the composite beam bending strength information, the composite beam shear strength information, or the composite beam lateral buckling strength information, the number of shear connectors, the composite beam rigidity information, and the required rigidity information. Among the comparison results and the like, necessary items are output to the display unit 33 (stiffness information output means).

For example, as a comparison result of the stiffness information of the composite beam and the required stiffness information, a safety factor for the required stiffness can be output. Further, by linking the unit price information to each member, it is possible to output the cost of the member used. Furthermore, it is also possible to perform the calculation under a plurality of conditions and simultaneously display the results for comparison. Needless to say, the result of each item can be stored in the storage unit 25 and can be transmitted to a printer or another terminal.

As described above, according to the present embodiment, when structural calculation is performed, the rigidity of a composite beam is directly calculated by adding the strength characteristics of the beam to the strength characteristics of the deck plate 1 and the concrete placed on the deck plate 1. Therefore, the strength of each of the girders 11 and the girders 13 can be calculated more accurately. In addition, since it is not necessary to separately calculate the rigidity of the composite beam, the labor of calculation can be saved.

Further, by selecting the deck plate corresponding to the shape of the beam, it becomes easy to select the deck plate, and it is possible to suppress erroneous selection. Further, the arrangement direction of the deck plate 1 is automatically determined without the user having to input it into the system, so that the labor of input can be saved. At this time, by making the side with the short beam interval the longitudinal direction of the deck plate 1, it is possible to apply the direction in which the strength of the deck plate 1 is high to the direction in which the strength of the structure is weak. The strength characteristics of can be improved.

Also, in order to compare the required rigidity of the structure and the calculated rigidity according to the type and application of the structure, it is easy to understand whether the selected conditions are applicable or whether it is an excessive design. be able to.

Further, since the number of shear connectors is calculated so that the floor slab can be fixed to the girder 11 with strength according to the rigidity of the composite beam, the upper flange of the steel beam can be efficiently integrated with the floor slab. You can
