摘要
基于虚功原理的有限元矩阵力法 ,推导出求解超静定桁架结构静力分析中的基本未知力的矩阵计算公式,该公式适用于编制程序。文中还以斜索桥为例进行计算 ,并与通用程序计算结果进行了比较。
Based on the finite element matrix_force method of the virtal work principle,the matrix_formula in the numeration of the unknown force in the static analysis of the exceed statically determinate truss structure is reasoned and used in programming.It calculates for the static analysis of cable_stayed bridge,and compares with the results of current programs.
