The detailed configuration and implementation of the present invention will be described with reference to the accompanying drawings.

First, FIG. 1 illustrates an execution screen of the present invention, and a screen for inputting basic information of a design service is shown.

2 to 7 illustrate screens for inputting various design constants applied in the course of design, and correspond to design constant input steps S10a, S10b, S10c, and S10d according to the flowcharts of FIGS. The process of inputting design criteria, safety factor, ground characteristics, material characteristics, coating thickness, and strength reduction coefficient, respectively, is shown.

The design standard refers to a specification that is called Codes of Practice. Various design standards applied by countries are stored in the form of an attached database in a program for carrying out the present invention. The design criteria will be selected.

Safety factor is a design element that is applied to the basic analysis from the geotechnical point of view, and as shown in FIG. 3, various risk factors such as bearing capacity, overturning, sliding, and up-lift of the foundation structure. 18 may be individually set, and the flow charts of FIGS. 18 to 20 are expressed as safety reference inputs S10d as a concept integrated with a strength reduction factor, which is a design element from a structural point of view.

4, as shown in the input screen of the ground characteristics, it is possible to calculate the ground characteristics through the soil characteristics and various empirical equations by directly inputting the soil bearing capacity determined through the field survey, or by selecting the detailed information input items. .

5 and 6 are input screens of material properties and coating thicknesses, respectively, and physical properties of materials constituting the basic structures such as concrete and reinforcing bars, and coating thicknesses which are distances between the surfaces of the reinforced concrete structures and the reinforcing bars are input.

7 is an input screen of the above-described strength reduction coefficient, in which the embodiment shown in the figure assumes the application of the ultimate strength design method, and the allowable stress design method or limit. If state design law is applied, it may be replaced by the input of safety factor.

8 is a screen in which load conditions, load combinations, etc., including load conditions such as self load, dead load, live load, wind load and earthquake load, are inputted directly, as shown in the drawing, or external data, that is, a diagram of an upper structure. And the load may be calculated by reading the physical property data and the like.

As described above, when the input of the design constant and load is completed, the basic specifications such as the shape and dimensions of the basic structure are set, and the user directly sets the basic specifications through the input screen as shown in FIG. Basic specifications may be set through online support of the same standard type database or the specification database 31 as shown in FIGS. 16 and 17.

When the basic specifications are set, the set basic specifications can be confirmed through the screen as shown in FIG. 11, thereby detecting an error or an outlier on the specification input.

On the other hand, Figure 12 is a screen for inputting a variety of setting values to be applied in the production of the quantity calculation and drawing after the design of the basic structure is completed, the rebar amount and the concrete volume percentage, drawing drawing standards, digging standards and the like is input.

After going through the above-described input and setting process, the design of the basic structure is completed through the optimization and decision support processes shown in FIGS. 19 and 20, respectively. The vector is stored and output in the form of the structural statement of FIG. 13, the back view of FIG. 14, and the quantity calculation report of FIG. 15 through the post-processing step S61.

Dependency can be reduced, and each detailed process will be described in detail through an execution step on a flowchart as follows.

Optimization based on the standard type database is performed by applying the standard types listed in the standard type database as shown in FIG. 10 step by step after input of the design constant and load is completed as shown in FIG. 19.

The initial application value of the standard type may be applied to the initial value of the arrangement of the standard type configured as shown in FIG. 10, or may be applied to the standard type closest to the standard outlined through the conditions such as effective bearing capacity and load.

Here, the standard type includes information such as the shape and dimensions of the enlarged base, the number and arrangement of peers as shown in FIG. 10, and a step (n) is provided for each standard type in the standard type database. As shown in Fig. 19, each step n may be declared as an array variable having n elements in the program.

The foundation structure is a composite structure of slab and the pier where the superstructure is installed, and it is not possible to increase or decrease only one dimension in the optimization process. Combinations can lead to excessive numbers of cases, which can take a lot of time and capacity to optimize.

Therefore, in the present invention, as shown in Figure 10, by setting the standard type combined with the expansion base and peer, it is possible to efficiently optimize by applying this step by step.

That is, as shown in Fig. 19, after applying the standard type drawn out from the standard type database to the basic specifications, the risk cross section is determined through design criteria, etc., and the rebar amount is calculated based on the required rigidity on the dangerous cross section to design the foundation. Apply.

Subsequently, review the ground stability of the design base, such as the above-mentioned support, conduction, activity, and subsidence, and if the structural stability of the basic structure is not reviewed through computational structural analysis, the process after the withdrawal of the standard type is repeated. Next, draw the standard type of the next step (n + 1) and apply it.

In the connection between the computer 20 and the server 30, an authentication process for preventing unauthorized access may be added, but this is a matter that can be selected by those skilled in the art to which the present invention pertains. No specific limitations of the claims are made.

When the computer 20 is connected to the server 30, the computer 20 transmits load information including the total load loaded on the basis of the design to the server 30, the server 30 to the transmitted load information The specification information of a predetermined range is withdrawn from the specification database 31 and transmitted to the computer 20.

Then, the computer 20 implements a screen as shown in FIG. 17 to display the received specification information. The user selects one of these specifications information and applies it as a specification of the design target basis or modifies and applies the above-described optimization design. Set the initial value of.

In the embodiment shown in Fig. 17, as the information contained in the specification database 31, the load information, the grade, the basic type, the number of the pier, the ground support force and the detailed dimensions are displayed. This means that the specification information provider provides the performance, and the user selects the specification information in consideration of the load approximation and the grade displayed on the screen.

That is, in the specification database 31 of the present invention, as shown in FIG. 20, when a plurality of users transmit the basic design result performed by the present invention to the server 30, the server 30 stores the built-in result. As a result, users with a large number of transmissions recognized high performance by acknowledging the performance of the corresponding design and marked it as a grade so that other users could refer to it.
