Description

  The present invention relates to a seismic isolation member arrangement plan support device and a seismic isolation member arrangement plan support program, and more particularly, a seismic isolation member arrangement plan that supports an optimal arrangement plan of seismic isolation members to be mounted on a building such as a high-rise building. The present invention relates to a support device and a seismic isolation member placement plan support program.

  Conventionally, by installing seismic isolation materials such as seismic isolation rubber and dampers on buildings such as detached houses, condominiums, and high-rise buildings, it has been possible to reduce the shaking of the building during an earthquake and prevent the building from collapsing and damaging. ing.

  When attaching seismic isolation members to a building, the type and size of seismic isolation members to be used and how the seismic isolation members are arranged are important. It is necessary to perform structural calculation according to the law and receive building confirmation, and it is necessary to confirm whether structural seismic isolation members are properly selected and arranged by structural calculation. As the types of this structural calculation, there are, for example, seismic isolation notification calculation prescribed in Ministry of Land, Infrastructure, Transport and Tourism Notification No. 2009, and time history response analysis defined in Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1461.

  In the seismic isolation notification calculation, a structure is replaced with one mass point, and the structure calculation is performed by a response spectrum analysis method based on an equivalent linearization method in a one-degree-of-freedom system. Time history response analysis, on the other hand, replaces structures with multi-mass system models, etc., and analyzes response acceleration, response displacement, etc. for input seismic waves from moment to moment, which is more detailed than seismic isolation calculation. Is possible.

Non-Patent Document 1 proposes a system that supports the optimization of the arrangement of the seismic isolation members by repeating the process of optimizing the arrangement of the seismic isolation members using the genetic algorithm (GA) and the seismic isolation notification calculation. Yes.
Nobuo Murota and Hisao Yamazaki, “Development of Seismic Isolation Member Placement Planning Support System”, Summary of Academic Lectures of Architectural Institute of Japan, August 2004, p. 367-368

  However, since the system described in Non-Patent Document 1 can only perform seismic isolation notification calculation, if you want to perform time history response analysis, create an analysis model of the seismic isolation layer and perform another time history response analysis. It was necessary for the system to perform time history response analysis, which was a cumbersome task for the designer.

  The seismic isolation notification calculation allows simple structural calculations, but since a sufficient safety margin is ensured, the size of the seismic isolation members tends to increase. While the arrangement of members may not be obtained, there is a merit that the design period can be greatly shortened. On the other hand, the time history response analysis is capable of more precise structural calculation than the seismic isolation calculation, but has the demerit that the analysis period is longer and the design period is longer.

  Therefore, as a designer, after optimizing the arrangement of the seismic isolation members to some extent by the seismic isolation notification calculation, it is preferable that detailed examination can be performed by a more detailed time history response analysis. An arrangement planning system capable of performing both time history response analysis has not yet been proposed.

  The present invention has been made to solve the above-described problems, and provides a seismic isolation member arrangement plan support apparatus and a seismic isolation member arrangement plan support program capable of executing both seismic isolation notification calculation and time history response analysis. For the purpose.

  In order to achieve the above object, a seismic isolation member arrangement planning support apparatus according to claim 1 comprises setting means for setting parameters necessary for structural calculation of a structure to which the seismic isolation member is attached, and a plurality of types of exemptions. Storage means for storing seismic isolation member data related to seismic members, and seismic isolation member arrangement for selecting seismic isolation members corresponding to the set parameters based on the seismic isolation member data and arranging them on each column of the structure Based on the means, the set parameters and the arrangement of the seismic isolation members, the first structure calculation means for calculating the structure by the first structural calculation method, and on the basis of the set parameters and the arrangement of the seismic isolation members, And a second structure calculation means for calculating a structure by a second structure calculation method different from the first structure calculation method.

  According to this invention, a setting means sets a parameter required for structure calculation of the structure which mounts a seismic isolation member. This parameter includes, for example, a building-related parameter, a ground-related parameter, and the like in addition to the position of the column of the structure, the load applied to the column, the type of seismic isolation member.

  The storage means stores in advance seismic isolation member data relating to a plurality of types of seismic isolation members, and the seismic isolation member arrangement means stores the seismic isolation members corresponding to the parameters set by the setting means. Select based on seismic member data and place on each column of structure.

  The first structure calculation means performs the structure calculation of the structure by the first structure calculation method based on the parameters set by the setting means and the arrangement of the seismic isolation members. For example, as described in claim 2, the first structural calculation method may be a seismic isolation notification calculation.

  The second structure calculation means calculates the structure by a second structure calculation method different from the first structure calculation method based on the set parameters and the arrangement of the seismic isolation members. The second structure calculation method can be a structure calculation method capable of performing a more detailed structure calculation than the first structure calculation method. For example, as described in claim 3, the second structure calculation method can be configured to be a time history response analysis.

  As described above, since both the first structural calculation method and the second structural calculation method can be executed, for example, the arrangement of the seismic isolation members is determined to some extent by the first structural calculation method. It is possible to execute the structure calculation by the second structure calculation method capable of performing a more detailed structure calculation than that of the first structure calculation method, and the convenience of the user can be improved.

  According to a fourth aspect of the present invention, the apparatus may further include an execution selection unit that selects which of the first structure calculation unit and the second structure calculation unit is to be executed.

  Thereby, the user can arbitrarily select which structural calculation method to use, and can cope with various user levels.

  According to a fifth aspect of the present invention, the apparatus further comprises a determination unit that determines whether or not a calculation result of the structure calculation by the first structure calculation unit satisfies a predetermined criterion, and the first structure calculation unit When the calculation result of the structure calculation satisfies a predetermined standard, the structure calculation by the second structure calculation means may be executed.

  Thereby, it is not necessary to check the calculation result by the first structural calculation method, and the convenience can be improved.

  According to a sixth aspect of the present invention, the seismic isolation member arranging unit may include an optimization unit that optimizes the arrangement of the seismic isolation member using a genetic algorithm.

  Thereby, it is not necessary for the user to reset the arrangement of the seismic isolation member one by one, and the arrangement of the seismic isolation member can be easily optimized.

  The seismic isolation member arrangement planning support program of the invention according to claim 7 stores a step of setting parameters necessary for structural calculation of a structure to which the seismic isolation member is attached, and a seismic isolation member corresponding to the set parameter. Selecting based on the seismic isolation member data relating to a plurality of types of seismic isolation members stored in the means, and arranging the seismic isolation members on each column of the structure; and, based on the set parameters and the location of the seismic isolation members, And a step of calculating the structure by a second structure calculation method different from the first structure calculation method based on the set parameters and the arrangement of the seismic isolation members. It is a computer-readable seismic isolation member arrangement planning support program for causing a computer to execute processing.

  According to this invention, since it is set as the structure which can perform both the 1st structure calculation method and the 2nd structure calculation method, a user's convenience can be improved.

  As described above, according to the present invention, both the seismic isolation notification calculation and the time history response analysis can be executed, and the convenience of the user can be greatly improved.

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

  FIG. 1 shows an outline of a personal computer as a seismic isolation member arrangement planning support apparatus according to the present invention. This personal computer includes a keyboard 10 for inputting data and the like, a computer main body 12 that optimizes the arrangement of base isolation members and performs structural calculations in accordance with a pre-stored base isolation member arrangement plan support program, and the calculation results of the computer main body 12 From the mouse 16 for performing operations such as moving the cursor displayed on the CRT 14 and the cursor displayed on the CRT 14 to a desired position, selecting, deselecting, and dragging the menu item or object at the cursor position. It is configured.

  The computer main body 12 includes a flexible disk unit (FDU) into which a flexible disk (FD) as a recording medium can be inserted and removed. Note that processing routines and the like described later can be read from and written to the flexible disk FD using the FDU. Therefore, a processing routine to be described later may be recorded in the FD in advance and the processing program recorded in the FD may be executed via the FDU. Further, the processing program may be stored (installed) in a mass storage device (not shown) such as a hard disk device provided in the computer main body 12 and executed. As recording media, there are optical discs such as CD-ROM and DVD-ROM, and magneto-optical discs such as MD and MO. When these are used, a CD-ROM device or DVD-ROM is used instead of or in addition to the FDU. A ROM device, MD device, MO device, or the like may be used.

  The hard disk of the computer main body 12 stores seismic isolation member data on a plurality of types of seismic isolation members and seismic isolation member arrangement plan support programs described later.

  Next, as an operation of the present embodiment, a processing routine of the seismic isolation member arrangement plan support program executed by the computer main body 12 will be described with reference to a flowchart shown in FIG. Note that this processing routine is executed when the execution of the seismic isolation member arrangement plan support program is instructed by the user, and is ended when the end is instructed by the user.

  In step 100, the position of the pillar of the structure to which the seismic isolation member (for example, laminated rubber or damper) is attached, the load (long-term load, additional load during earthquake, ie, short-term load), the type (kind) of the seismic isolation member, etc. Set the parameters. The type of the seismic isolation member can be classified according to the type and structure of the rubber used, for example, if it is a laminated rubber, such as a natural rubber-based laminated rubber, a lead plug insertion type laminated rubber, a high damping laminated rubber, or the like.

  The parameters are set by, for example, displaying a grid-like arrangement pattern 20 as shown in FIG. 3 on the CRT 14 and selecting the position where the column is installed, the load applied to the column, the type of seismic isolation member attached to the column, etc. This is done by letting the user set it. In addition, in the same figure, the corner | angular part (intersection of the vertical and horizontal dotted lines) of each grid | lattice is a position which can install a pillar, As an example, either of three types of seismic isolation members 22A-22C was set to each pillar. Indicates the state. For example, the user operates the mouse 16 to click the position where the column is installed, and sets the load applied to the column, the type of seismic isolation member to be mounted, and the like by operating the keyboard 10 and the mouse 16. Thereby, the load and the type of the seismic isolation member 22 to be mounted are set for each column.

  In addition to parameters related to seismic isolation members, the user is required to set parameters necessary for seismic isolation notification calculation and time history response analysis, such as building parameters, ground parameters, and input earthquake motion parameters. If these parameters are already stored in the hard disk of the computer main body 12, they may be set.

  Note that the processing in steps 100, 102, 106, and 120 can be the same as that described in Non-Patent Document 1 above.

  In step 102, the seismic isolation member corresponding to the parameter set in step 100 is obtained from the seismic isolation member data stored in the hard disk of the computer main body 12, and arranged on each column. The seismic isolation member data is a collection of data relating to characteristics (reference surface pressure, etc.) of the seismic isolation members of various types and sizes. Here, for example, a seismic isolation member having a reference surface pressure closest to the long-term surface pressure obtained from the long-term load among the set parameters is selected for each column.

  Next, in step 104, the user is allowed to select whether or not to perform the seismic isolation notification calculation. When the user instructs execution of the seismic isolation notification calculation, the process proceeds to step 106, and the execution of the seismic isolation notification calculation is performed. If the user has not instructed, the process proceeds to step 110.

  In step 106, a one-mass system vibration model is created based on the various parameters necessary for the seismic isolation notification calculation set in step 100 and the seismic isolation member arrangement pattern set in step 102, and the Ministry of Land, Infrastructure, Transport and Tourism announces the model. The seismic isolation notification calculation specified in 2009 is executed.

  In this seismic isolation notification calculation, for example, response displacement, response acceleration, laminar shear force coefficient, eccentricity, etc. are calculated.

  In step 108, the result of the seismic isolation notification calculation is displayed on the CRT 14. In this display, for example, in addition to each calculation result, it may be determined whether each calculation result satisfies a predetermined criterion, and the determination result may be displayed. Thereby, the user can easily grasp whether or not the result of the seismic isolation notification calculation is appropriate.

  Here, the user can check the result of the seismic isolation notification calculation and, if necessary, instruct the execution of the process for optimizing the arrangement of the seismic isolation member and the execution of the time history response analysis.

  Therefore, in step 110, it is determined whether or not the execution of the optimization process of the seismic isolation member is instructed by the user. When the execution of the optimization process is instructed, the process proceeds to step 120 and the optimization process is performed. If execution of is not instructed by the user, the process proceeds to step 112.

  In step 120, the process of optimizing the arrangement of the seismic isolation members is performed using a genetic algorithm (GA). This process can be the same process as described in Non-Patent Document 1, for example. That is, first, the size of the seismic isolation member initially set in step 102 is set as a gene candidate with a total of three sizes of seismic isolation members in the upper and lower sizes. Then, the optimum solution, that is, for example, the combination of the seismic isolation members that minimizes the response acceleration and the response displacement is searched by a predetermined fitness function. When the optimization process ends, the process returns to step 104 and the same process as described above is repeated.

  On the other hand, in step 112, it is determined whether or not the execution of the time history response analysis is instructed by the user. When the execution of the time history response analysis is instructed, the process proceeds to step 114, and the execution of the time history response analysis is performed. If not, the process returns to step 104 and repeats the same processing as described above.

  In step 114, a multi-mass point vibration model is created based on the various parameters related to the time history response analysis set in step 100 and the current arrangement pattern of the seismic isolation member. Perform the specified time history response analysis. That is, response values such as response displacement and response acceleration are calculated from time to time by integrating the equations of motion of the vibration model that receives input seismic motion over time.

  In step 116, the result of the time history response analysis is displayed on the CRT 14. In this display, for example, a time history of response values such as response acceleration is displayed. Thereby, the response value which changes every moment can be easily confirmed.

  Here, the user can check the result of the time history response analysis, and can instruct execution of the process of optimizing the arrangement of the seismic isolation members if necessary.

  Therefore, in step 118, it is determined whether or not the execution of the optimization process for the seismic isolation member is instructed by the user. When the execution of the optimization process is instructed, the process proceeds to step 120, and the optimization process is performed. If the execution of is not instructed by the user, the process proceeds to step 104 and the same processing as described above is repeated.

  As described above, in the present embodiment, not only the seismic isolation notification calculation but also the execution of the time history response analysis can be selected and executed by the user. Accordingly, it is possible to perform detailed examination by more precise time history response analysis after optimizing the arrangement of the seismic isolation members to some extent by seismic isolation notification calculation that allows simple structural calculation. For this reason, structure calculation can be performed efficiently and the design man-hour can be greatly reduced.

  In the present embodiment, the case where optimization of the arrangement of the seismic isolation member is performed using a genetic algorithm has been described. However, the present invention is not limited thereto, and the user may be allowed to set the selection and arrangement of the seismic isolation member. Good.

  Moreover, although this embodiment demonstrated the case where a user selected whether to perform a seismic isolation notification calculation or a time history response analysis, you may enable it to select the following automatic execution processes. For example, if a parameter is set, the seismic isolation calculation is automatically executed, and it is determined whether or not each calculation result satisfies a predetermined standard. Optimize the seismic isolation member placement by genetic algorithm. When all the calculation results satisfy a predetermined standard, the time history response analysis is automatically performed and the result is displayed. Thereby, a user's convenience can be improved significantly.
