悬索结构的非线性分析程序

一、引言悬索结构的分析方法,可分成连续法和离散法两类。运用连续化方法,计算方便,但通用性差,且计算精度较难保证,目前,只能用来分析索桁架和单层正交索网形式的结构。与连续法相比,离散法具有通用性好、计算精度高的特点,因而特别适合于对悬索结构的研

Nonlinear Analysis Computer Program of Cable Structure

Based on the theory of finite element method of one dimensional strai- ght element,the stiffness matrix and the equivalent load vector of cable ele- ment,in which the prestress and the change in temperature are considered, are presented and the computer program of nonlinear static analysis of cable structure with displacement method is described in this paper under the assum- ption of elastic behavior and small strain of cable element.The use of the program shows its high calculation accuracy and wide applicability.
