摘　　要：随着电力、交通、石油、化工业的快速发展 ,在实际工程设计中所遇到的大型钢结构桁架设计项目也越来越多。将计算结构力学的矩阵分析法引入到大型钢结构桁架的静力分析和力学计算之中 ,并运用计算机高级语言编制了大型钢结构桁架的静力分析和力学计算程序 ,该计算程序能方便、快捷地计算出空间桁架的节点力和立柱、腹杆的内力 ,进而校核钢结构桁架的强度、刚度和结构稳定性。并运用AutoCAD工具软件绘制出钢结构桁架的工作图。设计方法具有一定的通用性 ,对提高钢结构桁架的设计效率 。As rapidly developing of electric power, traffic, petrochemical industry, design project of large-scale steel structure truss becomes more and more in practical engineering design. In this paper, the computer programming language has been used. Based on matrix analysis method in computational structure mechanics, a program of static analysis and calculation has been compiled for large-scale steel structure trusses. The program can calculate the forces in nodes and the internal forces in stands in whole spacial trusses, thus it can be used to check the intensity, rigidity and structural stability of the steel structure truss. And AutoCAD tool software is utilized to draw the working drawing of steel structure truss. This design method is a general one and has practical significance for raising design efficiency of steel structure truss, shortening design cycle and raising economic efficiency.
