Abstract

PURPOSE:To obtain a desired graphic form at a low price without using a digital plotter nor a graphic display by adding a simple deciding means and a graphic output means to an existing structure analysis system. CONSTITUTION:Input data including information on the shape, material, load, etc. of a structure also includes information (switch information) for deciding whether input data information and analysis information should be outputted to a printer form or no Switch information is decided with respect to the input data information. If the output of the switch information is decided, a graphic form is drawn on the printer form based on the shape information of the structure. While analysis processing is carried out if the output of the information is not decided. Then the switch information is decided in terms of the analysis information. If the output of the switch information is decided, the graphic output of the analysis information is carried out. Then the processing is completed if the output of the information is not decided. Each processing can be easily carried out by a computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structural analysis system used mainly in the fields of architecture, civil engineering, and machinery.

[Prior art] Generally, in this type of structural analysis system, the finite element method is often adopted as the analysis method, and as the scale of the target model increases, that is, as the number of nodes increases, the input data The amount of data and the amount of output data (analysis information) are also extremely large. These input/output data are normally output as numerical information on print paper, but in order to make it easier to visually judge this, numerical information is output using peripheral devices such as Digital 10 Tsuta or Graphic 11/K Display. Graphical representation of is widely practiced.

[Problem that the invention seeks to solve]

However, the peripheral equipment used in the conventional structural analysis system described above is not necessarily inexpensive, and there is a problem in that it costs a considerable amount of money to output the intended graphic.

[Means for Solving the Problems] The system of the present invention inputs input data information including shape information, material information, load information, etc. of a structure into an electronic computer to obtain displacement information and stress information of the structure. In a structural analysis system that solves analysis information included and outputs the result as numerical information on printer paper, it is determined whether at least one of the input data information and the analysis information is output as a figure on printer paper. The apparatus includes a determining means, and an output means for outputting the corresponding information as a graphic onto printer paper when the determining means determines that the information should be output.

〔Example〕

Next, the present invention will be explained with reference to the drawings. 6 Figure 1 shows a flowchart of an embodiment of the present invention. 6 Shape information, material information, load information, etc. of the structure read in with step 1. The input data includes information on whether to output the input data information and analysis information on printer paper (
switch information).

In Step 2, the switch information is determined with respect to the input data information, and if it is determined to output based on this determination, in Step 3, the printer paper is determined from the information (shape information) representing the position of the node in the input data information. A process of drawing a figure on top is performed (step 3). Further, if it is determined by this determination that the output is not to be performed, the process proceeds to step 4, the analysis process. Even after the analysis process, switch information is determined in step 5 regarding the analysis information, and if it is determined that the switch information should be outputted, the step 6 outputs the analysis information in a graphic form. Furthermore, if it is determined through this determination that the output is not to be performed, the process is terminated. Note that each process of steps 1 to 6 can be easily performed by a normal means for a computer.

〔Effect of the invention〕

As explained above, the present invention adds a simple judgment means and a figure output means to an existing structural analysis system, thereby making it possible to inexpensively produce a desired figure without the need for a digital plotter or graphic display. There is an effect that can be obtained.

Claims (1)

[Claims] Input data information including shape information, material information, load information, etc. of the structure is input into an electronic computer to solve analysis information including displacement information and stress information of the structure, and the results are expressed numerically. In a structural analysis system that outputs information on printer paper, the system includes: a determination unit that determines whether or not at least one of the input data information and the analysis information should be output as a figure on printer paper; and a structure that is determined to be output by the determination unit. and output means for outputting corresponding information in the form of figures on printer paper.
