摘　　要：对一种新型输电杆塔钢管杆塔进行几何非线性有限元分析 ,用VisualBasic 5 .0和DigitalFortran 5 .0混合编程 ,编制了有限元分析软件 ,解决了传统设计线性计算的不足 ,计算结果满足钢管杆塔设计分析的需要 .Geometric nonlinear finite element analysis of a new type of transmission tower, a pole_tower made of steel tubes, is carried out. And a software of finite element analysis is programmed with mixed languages of Visual Basic 5.0 and Digital Fortran 5.0. It overcomed the shortcomings of calculation with linear FEM in traditional design, and the result can satisfy the needs of the design of steel tube pole_towers.
