3A and 3B are detailed control flowcharts illustrating the structure calculation service method of FIG. 2.

As shown, first, the user selects the type of structure for which the structure is to be calculated (step S111). In one embodiment according to the present invention, it is assumed that the structure to be calculated by the retaining wall. The user selects a condition of the retaining wall (step S112). At this time, the conditions to select include ① retaining wall type, ② front and rear cross-sectional conditions, and ③ pile existence. Before inputting data, it is checked whether there is already input data (step S113).

In the determination step (S113), if there is data is edited (step S114). At this time, the detailed data includes 'specification standards', 'supporting ground conditions', 'earthquake class', horizontal restraint conditions, land survey results, 'structural dimensions', 'loading loads', pile-related data, etc. .

However, if there is no data in the determination step (S113), the structure calculation data of the selected retaining wall is initially input (step S115). Then, the earth pressure, safety and cross-sectional structure calculation is performed using this data (step S116), and the earth pressure calculation is confirmed among the calculated results (step S117). At this time, the contents to be checked include self-weight, thick-filled soil, earth pressure, reload, seismic force, load and water pressure. After confirming the earth pressure calculation result, the stability calculation result is reviewed. At this time, the safety of the safety factor values, such as falling, ground bearing capacity and sliding is examined (S118). Here, the stability calculation review includes 'consideration review', 'stable review of activities' and ground support review as shown.

If the result of the stability is determined (step S119), and the result of the stability calculation is unsatisfactory, the user data correction menu is selected from the data correction menu (step S120), and the structure calculation data is modified to calculate the structure calculation. Return to step S112 to perform again, or select the safety factor optimization menu to enter the user safety factor expected value (step S121), perform the optimization calculation (step S122), edit the structure calculation data using the optimization value again Repeat from step S116.

On the other hand, in the step S119, when the result of the stability calculation is satisfied, the cross-sectional calculation review process. In this process, the work to be performed is to perform a balance check, a member force calculation, a cross-sectional review, and a coupling rebar review in the state multiplied by the load factor (step S124). After the review, the result is determined (step S125). If the result is dissatisfied with the result of the section, the process returns to step S112. If the result is satisfied, the final structure calculation data is determined and the input data is determined. Stored in the user database (DB) 112 (step S126). Then, the structured bill file is generated using the determined data (step S127), and it is determined whether or not the service is terminated (step S128), and when the user selects the service "① structural calculation service", the service is terminated and returned ( Step S129), and when the user selects the service ② drawing automatic drawing service or ④ drawing automatic drawing + design statement service, after transmitting the data necessary for the automatic drawing drawing to the ② drawing drawing service (step S130), FIG. Return to next step (step S131).

As shown, by determining the selection number of the main service (step S161), the selected service type is one of ① structural calculation service, ② structural calculation + drawing automatic drawing service, ④ structural calculation + drawing automatic drawing + design statement service In one case, the data necessary for drawing a drawing among the data stored in the structure calculation is read from the user database (DB) 112 (step S162). Then, additional input of necessary data is received from the user (step S162). At this time, the additional data received includes retaining wall width data, retaining wall height data, retaining wall reinforcement data, and retaining wall foundation setting data. In operation 164, the two pieces of data are stored by assigning a specific database identifier (DB ID) to the user database.

On the other hand, in step S161, if the selected service type is (3) drawing automatic drawing + design history service, the user receives all the data necessary for drawing drawings (step S165). At this time, the input data is retaining wall width data, retaining wall height data, retaining wall reinforcement data, and retaining wall basic setting data. The data is stored in a user database by assigning a specific database identifier (DB ID) (step S164).

At this time, the web server 230 establishes a socket connection with the application processing unit 310 of the service processing means 300 through the CAD drawing data transmission / reception processor 250, and receives data input from the user through this connection. To pass. The service processing means 300 calls the CAD drawing module 321 using the received data to start the automatic drawing generation process (step S166). Here, a print file PLT such as a CAD format drawing file DWG, a file format DWF viewable on the web, and a file for print output is generated (step S167). In the generated CAD file drawing, a standard section view, a general view, a wall front view, a bottom plan view, a PVC detail view, a reinforcement detail view, a reinforcing bar material bill, and a quantity of paper clip are drawn. The application processor 310 calls the FTP client 360 through the effect interface 340 and transfers the generated file to the predetermined directory 270 of the service provider means 200 by FTP.

If the user wants to simply view the drawing file generated through the web, the user can apply for it and view the drawing of the user's own DWF file format through the user's own viewer (Step S168). Then, if you want to end the service, return to the next process of Figure 2 (step S170), and if the type of service is the drawing automatic drawing + design history service or ④ structural calculation + drawing automatic drawing + design statement service design statement After transmitting the necessary data when generating a design statement service as shown (step S171), and returns to the next process of Figure 2 (step S172).

FIG. 5 is a control flowchart illustrating the design detail service method of FIG. 2 in detail.

As shown in the figure, the data generated and transmitted in step S126 of FIG. 3B and the price data are read from the user database 210 (step S181). At this time, the read data includes data such as 'age unit price', 'price data', 'medium term data' and 'unit price data', and the drawing quantity data is the data processed and transmitted by the automatic drawing service. The user receives input of additional data necessary for generating the design history (step S182). The additional data received at this time are data on 'project name', 'dig', 'backfill and compaction', 'choose cotton', 'rebar transportation', 'crushed rubble', and 'scrap metal'. The design statement generation processor is executed from the statement generation module 350 of the service processing means 300 to automatically generate the design statement file and the preview file (step S184). The contents of the design bill consist of the construction unit's market wage unit price, price survey table, mid-term fee, and unit price calculation. The generated design statement can be output to the screen through the user's web and checked (S184).

The application processing unit 310 of the service processing means 300 calls the FTP client 360 through the expert interface 340 and transfers the generated file to a predetermined directory of the service provider means 200 by FTP. Return to the next process of (S185).
