空间网架计算机辅助设计系统STAP

本文介绍一个空间网架计算机辅助设计系统STAP,它可以安装在具有256K字节以上的IBM—PC/XT及其兼容机上并需附加配置DXY—800A绘图仪。这个系统可以根据对网架结构的初步选型,进行对输入数据错误的搜索;对内力与应力进行有限元分析;选择截面尺寸;绘制結构内力及应力分布图形;打印内力,应力及材料表格;还可自动在屏幕或打印机,绘图仪上绘制结构各种视图;标注尺寸线等。对几种常用的网架形式还可以实现自动编码,自动形成结点坐标值等。具有成本低,见效快,直观性强的优点。本系统在对40多个实际工程和140多个标准图计算使用后表明,性能稳定,结果可靠,使用方便。

CAD SYSTEM STAP FOR SPACE GRID STRUCTURES

This paper presents a computer-aided design system for the analysis of space grid structures using a micro-computer. This system can be installed in an IBM-PC/XT computer with 256kB and its compatible computer systems. A DXY-800A plotter must be attached to it. According to the selection of structural types this system can detect errors of input data, analyze the internal forces in the member by finite element method, select the dimensions of areas, plot distributive views of internal forces, print lists of member internal forces and stresses, plot various structural views, and mark dimensional lines. For some grid structures generally used this system can perform numeration automatically. The calculations of 40 practical applications and more than 140 standardized figures show that this system is steady, economical and convenient.
