Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to history management of a design support system for performing a plurality of types of structural calculations on data items.

[0002]

2. Description of the Related Art A structural calculation system for creating a structural calculation application for a building confirmation application has a causal relationship between input data and calculation result data in order to prevent intentional misuse (based on input data Calculation result data is required). Since the conventional structural calculation system is batch processing, structural calculation is performed consistently from input data to calculation results. Therefore, it was not possible to change the input data in the middle of designing, and if there was a change, the structural calculation was redone consistently from the beginning. In particular, in the case of a large-scale building, all the calculations had to be redone even if the design was partially changed, so the design efficiency was poor and it was difficult to shorten the design time.

[0003]

[Problems to be Solved by the Invention] When an interactive design is intended, if the input data is changed in the middle of the design, a complete calculation will be performed between the result data of the calculation already performed before the change and the re-input data. The causal relationship will not hold (result data is not calculated based on re-input data). However, in ordinary design, the establishment of this causal relationship is recognized as an engineering judgment within a certain allowable range. However, there is no effective change data management method in the process of structural design by computer. Therefore, there is a problem that structural calculation must be performed consistently from the input to the result.

[0004]

[0006]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings. <a> Outline of history management device of design support system When the history management device of the design support system does not establish a causal relationship with the calculation result that has been performed before the change due to the change of the input data (the calculation result is changed If not performed based on the input data), the user can be notified within the system. In particular, the generation management function of the database is effectively used to manage the data content changed for each generation, and the design process is handled for each calculation (calculation stage unit), and the design progress status is entered at the model input time. , The calculation end time, each generation number, and the causal relationship between the input data and the calculation result are managed on the same database.

The outline of the overall configuration of the design support system 1 is shown in FIGS. This system includes a general database 010 storing common data, a project database 020 storing data to be designed, a model input 110 for inputting a construction model,
The model includes a structural calculation system 120 that performs structural calculation of the model, an input data batch history check final confirmation system 130 that manages the history between changed generations, and the like.
The history management device includes a unit of history management in the design support system 1.

<B> General Database The general database 010 stores common data. Among them, the input data management table 011 includes, for each data item, change contents of the input data used in the structural calculation, a confirmation solid flag indicating whether or not recalculation is necessary due to the change, and the like. (See Table 1).
Symbols such as a, b, and c in the confirmation solid flag column indicate types of calculation stages, and are described in detail in the section of the structural calculation system.

[Table 1]

<C> Project Database The project database 020 stores data to be designed. Among them, building model 0
21 stores the building data necessary for the structural calculation input and changed by the model input 110, the attribute data such as the calculation condition, and the calculation result. The input data monitoring model 022 has a model input 11 when the input data is changed.
The state of the causal relationship between the update data checked by the data update monitoring system 111 in 0 and the structural calculation result is stored.

In this case, when writing to the building model 020, the contents updated in the update mode are written to a new generation. In the design progress monitoring model 023, the time of data input update, the generation number (number of times of update), and the calculation end time of each structural calculation stage are recorded. The intergenerational history management model 024 manages the updated contents. .

<D> Input Model As described above, the input model 110 inputs and changes attribute data such as building data and calculation conditions necessary for structural calculation and stores them in the project database 020. The data update monitoring system 111 checks the causal relationship between the update data and the structural calculation result, and checks the input monitoring model 022.
Record the condition in.

<E> Structural calculation system The structural calculation system 120 is divided into, for example, seven design stages, and refers to the input data of building data and attribute data from the project database 020 and the structural calculation results that have already been performed. The calculation result is stored in the project database 020. The seven stages include a load calculation stage (a) for the first stage, a stiffness calculation stage (b) for the second stage, and a third stage.
The stage is a stress calculation stage (c), the fourth stage is a shape factor calculation stage (d), the fifth stage is a section selection calculation stage (e), the sixth stage is a section verification calculation stage (f), and the seventh stage is possessed. Strength calculation stage (g)
Is. The calculation execution permission system 121 gives an instruction to execute the calculation and determines whether or not a causal relationship is established between the input data referred to in the calculation stage instructed to execute and the calculation result.

<F> Input data batch history check final confirmation system Input data batch history check final confirmation system 130
Refers to all the input data for each generation changed from the intergenerational history management model 024, and the input management table 011
Check with. Based on this result, a table of data items, contents, definition contents, calculation check flags is created (see Table 2), and if a causal relationship is not established between the changed data and the calculation result of each calculation stage, use Automatically notify the person.

[Table 2]

The flow of design processing will be described below with reference to the drawings (see FIG. 5).

<a> Data input The data of the column code 1C1 is, for example, the data of the generation 8,
Cross-sectional shape is 600 x 600, the number of main bars is 3 in the X direction, Y
There are three directions (see FIG. 3A). Also, the pillar code 1
The data of C2 is also the data of generation 8, and the cross-sectional shape is 600 × 600, the number of main bars is three in the X direction, and three in the Y direction as in the case of the column code 1C1 (see FIG. 4A). These input data are stored in the project database 020 together with other building data and attribute data using the model input 110 (S1). At this time, the input time "2-Aug-1992 09:30:09" and the generation number "8" are recorded in the design progress monitoring model 023 (see Table 3).

[Table 3]

<B> Structural Calculation For the input data, the necessary calculation stages a to d and f are selected, and load calculation, rigidity calculation, stress calculation, shape calculation, and cross-section verification calculation are performed (S2). At that time, the input time, the calculation end time, and the generation number are referred to from Table 3 of the design progress monitoring model 023. Also, it is checked whether the selected calculation stage has been performed before and the order of the calculation stages is correct. Then, the calculation is executed and the calculation end time and the generation number are written in the design progress monitoring model 023 for each calculation stage (see Table 3).

<C> Consideration of Calculation Results When the results of the cross-section calculations are considered (S3), for example, it is impossible to design RC columns with the data of generation 8 of column codes 1C1 and 1C2. 3 (B) and FIG.
Decide to change to (B).

<D> Data change When changing input data such as building data and calculation conditions,
Model input 110, project database 0
Only the updated contents are stored in 20 (S4). Pillar code 1C
In the case of 1, the cross-sectional shape of the RC column list is changed from 600 × 600 to 700 × 700 by the model input 110, and in the case of the column code 1C2, the number of main bars in the X direction is changed from 3 to 4. For these changed data items, a change flag is set in the table corresponding to the correction code of the input management table 011. At the end of input, the design progress monitoring model 02
From 2 (see Table 3), it is confirmed that the calculation stages a to d and f have been completed. Next, referring to the input data management table 011 (see Table 1) for the confirmation solid flag corresponding to the data item and the change content from each change flag, is the causal relationship established with the calculation result of the calculation stage already performed? To check. Then, in the case of the change of the pillar code 1C1, it is understood that it corresponds to the correction code 25 because it is a cross-section change, and the confirmation solid flag is all "2", and it is determined that recalculation is necessary for all calculation stages. Has been done. In addition, in the case of the change of the pillar code 1C2, it is understood that it corresponds to the correction code 26 because it is the change of the number of main lines, and the confirmation solid flag has the cross-section verification and the holding strength of "2". , It is determined that recalculation is necessary.

When the column code 1C1 is changed, it is necessary to carry out the structure calculation stages a to d and f, and the confirmation solid flag 2 is set by judging the judgment result and the necessity of the structure calculation. Further, in the case of the change of the pillar code 1C2, it is necessary to execute the structural calculation stage f, and the confirmation solid flag 2 is set and recorded in the input data monitoring model 022 (Table 4).

[Table 4]

<E> Structural Calculation The calculation execution permission system 121 again gives an instruction to execute the necessary structural calculation from the calculation execution instruction menu (see Table 5) (S5). Consider the input data monitoring model (Table 4) to determine the need to perform the indicated structural calculation stage. In this case, the cross section verification stage f is executed.

[Table 5]

When it is determined that the structural calculation cannot be executed again, the changed data confirmation list (see Table 6) is automatically notified to the user.

[Table 6]

In the case of the example of Table 6, the execution instruction of the calculation stage f is issued, but in the contents of the input data monitoring model of Table 4,
Since the modification code is "25" and the confirmation solid flag is "222220", the calculation stages a to d do not establish the causal relationship between the input data and the calculation result because the pillar code 1C1 is changed. Recalculation is required. In addition, since the modification code is “26” and the confirmation solid flag is “1111020”, the change of the pillar code 1C2 does not require execution of the calculation stages a to e before the calculation stage e. Therefore, when the user follows this determination, the column code 1C1
On the other hand, the calculation stages a to d are recalculated. However, if engineering judgment or immediate result is desired, the judgment may be ignored and only the designated stage may be executed.

In this case, the input data batch history check / final confirmation system 130 intentionally stops the incorrect use. For example, when the user selects the calculation stage (section verification stage f), the input data monitoring model 022 (see Table 4) is used to check the feasibility. Then, according to the design progress monitoring model 023, the input time,
The calculation end time and the generation number are referenced (see Table 3).
Also, if the selected calculation stage was previously performed,
The order of the calculation stages is checked for correctness. Since the data is changed after the calculation is executed, the correction code and the confirmation solid flag are referred to by the input data monitoring model 022 (see Table 4). As a result, the calculation execution permission system 12
In No. 1, it is determined to be unexecutable, and the change data confirmation list (see Table 6) is automatically notified to the user. However, when the cross-section verification calculation is executed by the designer's engineering judgment, the calculation end time and the generation number are written in the design progress monitoring model 023 (see Table 3).

<F> Consideration of Calculation Results Again It is judged whether the changed portion is good (S6), and if necessary, the data is changed again. At this time, the result of the calculation stage (cross-section verification calculation) performed may be considered.

<G> Output of calculation form Batch confirmation of input data Final confirmation system 130
Refers to all input data for each generation changed from all intergenerational history management models 024, collates and checks the input management table 011 to check "code", "item", "contents". , "Definition content", and "calculation stage ag" are created in Table 2, and the user is automatically notified of the causal relationship between the changed data and the result of each calculation stage (S7). . The last item is the calculation end confirmation column. The symbol "abcdefg" corresponds to each stage, and the symbol "*" indicates that there is no causal relationship between the changed data and the calculation results that have already been calculated. It means that the calculation has not been performed). In the "definition contents", the lower row shows the data of the generation number "8", and the upper row shows the data of the generation number "9" after the change. In this example, it is shown that the calculation stages a to d required by the change of the code 25 have not been recalculated yet.

[0026]

According to the present invention, the following special effects can be obtained. <A> Even if the input data of the design support system is changed on the way, it is automatically managed in the system without the user being aware of the causal relationship with the calculation result already performed. As a result, it is possible to effectively use the advantages of the conversational type, and the system automatically determines from which calculation stage the recalculation should be performed when the input data is changed during the design. Therefore, the user can entrust the system to troublesome data management, facilitate repeated examination, and perform high-quality design in a short time.
