Description

  The present invention relates to an information generation apparatus for structural analysis of a building, an information generation method for structural analysis, and an information generation program for structural analysis, and more particularly, based on CAD (Computer Aided Design) information for design design of a building. The present invention relates to a structure analysis information generation device, a structure analysis information generation method, and a structure analysis information generation program that generate information for building structure analysis.

  Conventionally, in building design work, the design designer responsible for determining the building shape and finish specifications, etc., and whether the building can withstand earthquakes, etc. The design work is carried out jointly with the structural designer in charge of the decision.

  Here, each person in charge of design works using a computer, but despite being doing the design work for the same building, each person individually inputs building information into the computer. Is the current situation.

  In other words, it is the present situation that the design designer passes the building drawing input by the design design CAD to the structural designer as paper or electronic data, and the structural designer inputs the building information to the structural design system again. is there. Therefore, despite the fact that the design designer has input the building information into the computer, the structural designer has to input the same information in a different form.

  On the other hand, in recent years, software called object CAD has appeared mainly in the field of design design, and it is not a substitute for a simple drafter (drawing machine) like conventional CAD, but can recognize each member constituting a building. It is becoming. That is, in the case of a conventional CAD, a computer can recognize only as a collection of lines, although it can be recognized as a pillar, a wall or the like by looking at a drawing created by CAD. On the other hand, in the object CAD, there is a big difference that the computer recognizes a column as a column and a beam as a beam. On the other hand, in the field of structural design, the software originally recognizes such building members individually.

  However, it is still difficult to exchange data between the information by the object CAD input by the design designer and the information for structural analysis input by the structural designer because of the difference in the viewpoint of the building.

  In order to solve these problems, some structural design systems implement a mechanism for assisting input using a drawing created by CAD for design design as a background. If this mechanism is used, the input work of the structural designer can be reduced to some extent. However, even in this case, since it is still necessary to manually input the data, it is considered that a complicated operation for inputting the opening information of the wall and the slab is generated and the structural calculation is relatively less affected. It is a situation where the column shift (fine adjustment of the horizontal position) is not input. For this reason, the information for structural analysis that should be effectively used in the later process of the design is input only incompletely because the input work is complicated and cannot be effectively used. However, there are also situations where you need to enter building information in two or three layers.

Therefore, the technique disclosed in Patent Document 1 tries to reduce such problems by exchanging frame information (information on building structures) between the building DB-CAD and the structure DB-CAD.
JP2003-141191A

  However, in the technique disclosed in Patent Document 1, the frame information from the architectural DB-CAD to the structural DB-CAD is simply superimposed using the function of the multilayer layer of the structural DB-CAD, The designer can only obtain the effect that the structural information from the building DB-CAD and the structural body information input by the designer can be superposed on each other and visually confirm the alignment state. Is limited. The same applies to the use of the frame information from the structural DB-CAD to the architectural DB-CAD, and this mechanism is essentially the same as the structure of the structural design system described above.

  For this reason, there is a demand for a technique for generating structure analysis information directly and automatically from CAD information for design design.

  Also, the design design object CAD program and the structural design CAD program described above are installed in the program area PG of the hard disk 28.

  Next, with reference to FIG. 8, the operation of the structural analysis information generating apparatus 10 according to the present embodiment will be described. FIG. 8 shows the flow of processing of the structural analysis information generation processing program executed by the CPU 22 of the structural analysis information generation apparatus 10 when an execution instruction is input by the user operating the keyboard 14, mouse 16, or the like.

Here, in order to avoid complications, a case will be described in which the design designer CAD information database DB1 is constructed in advance by the design designer using the design design object CAD program. Furthermore, here, a case will be described in which a building to be processed in the structure analysis information generation processing program is designated in advance by the user by operating the keyboard 14, mouse 16, or the like.

  First, in step 100 of the figure, design design CAD information (hereinafter referred to as “processing object CAD information”) corresponding to the building to be processed (hereinafter referred to as “processing object building”) is stored in the hard disk 28. Read from the design design CAD information database DB1, and in the next step 102, a core / floor level information generation processing routine program is executed.

  Hereinafter, the core / floor level information generation processing routine program will be described with reference to FIG. FIG. 9 is a flowchart showing a flow of processing of the core / floor level information generation processing routine / program. The program is also stored in the program area PG of the hard disk 28 in advance.

In step 200 in the figure, it is determined whether or not the column information is present in the processing target CAD information. If the determination is affirmative, the process proceeds to step 202 and any one included in the processing target CAD information. Whether or not the center coordinates of the processing target column indicated by the column information of the column (hereinafter referred to as “processing target column”) is positioned within the range of the core candidates generated by the processing of step 206 described later. If the determination is affirmative, the process proceeds to step 204. If the determination is negative, the process proceeds to step 206. In the present embodiment, the determination by the processing in step 202 is performed using the following equations (1) and (2). Here, in Equations (1) and (2), X is the X coordinate of the center position of the processing target column, Y is the Y coordinate of the center position of the processing target column, C _X is the X coordinate of the center candidate, and C _Y represents the Y coordinate of the core candidate, D represents the width of the column to be processed, and α represents a predetermined coefficient (D / 2 in the present embodiment).

FIG. 10 shows the cores defined by the equations (1) and (2) (in the figure, “1”, “2”, “3”, “A”, “B”, “C”). A schematic plan view showing the determination range is shown.

  In addition, when the execution of the main line / floor level information generation processing routine / program is started and the process of this step 202 is executed for the first time, there is no core candidate, so a negative determination is made in step 202. Will be.

  In step 204, the processing target column is related to the core candidate determined in step 202 that the processing target column is positioned within the range, and then the process proceeds to step 208, while in step 206 Assuming that the processing target column is a new core candidate, information indicating that the processing target column is a core candidate is generated, and then the process proceeds to step 208.

  In step 208, it is determined whether or not the processing in steps 202 to 206 has been completed for all the column information included in the processing target CAD information. If the determination is negative, the processing returns to step 202, and the above steps are performed again. While executing the processing of 202 to 206, the process proceeds to step 210 when an affirmative determination is made. Note that when the processes in steps 202 to 208 are repeatedly executed, a column that has not been set as a processing target until then is set as a processing target column.

  In step 210, a core is determined based on the core candidates obtained by the above processing and the processing target column related thereto, and after generating information indicating the determined core, the process proceeds to step 220. In the present embodiment, as a method of generating information indicating the street core by the process of step 210, for each street candidate, the processing target column that is a street center candidate and the street center candidate are associated with each other. Although the method of generating the average value of each position coordinate of the processing target column as information indicating the position of the core is not limited to this, for example, the processing target that is a core candidate for each core candidate Among the columns to be processed associated with the column and the core candidate, the coordinate value (coordinate value in the direction orthogonal to the axis direction of the core) having the largest number of columns having the same position coordinate is used as the core. Other generation methods such as a form for generating the information indicating the position can also be applied.

  On the other hand, if a negative determination is made in step 200, the process proceeds to step 212. As shown in the schematic plan view of FIG. 11A as an example, the outer wall of the processing target building is based on the wall information in the processing target CAD information. And is generated as information indicating the position of the lead through the extracted position coordinates of the wall center of the outer wall.

However, the present invention is not limited to this, and information indicating the material of the wall is registered in association with each wall in the design design CAD information database DB1. Alternatively, it may be determined whether the structure wall is based on the information indicating the material.

  In step 602, after generating the information for structural analysis which shows the structural wall determined to exist in the process of the said step 600, it transfers to step 604.
