| 摘 要： | 本文从广义逆矩阵理论出发,利用变形协调条件,用 Moore-Penrose 广义逆直接解桁架结构的平衡方程组,而不象经典力法那样先选择基本结构再求解内力。广义逆矩阵力法使静定桁架和超静定桁架的力法计算全部概括统一起来。文中给出计算公式并附算例。

| Abstract: | Based on the theory of generalized inverse of matrices and on the utilization
of compatibility,a method of solving the equilibrium equations by Moore-Penrose
generalized inverse of the coefficient matrix is given.The procedure of analyzing
a truss is different from the classical force method,in which a statically
determinate structure must be selected first.The formulae for calculating internal
forces of statically determinate and indeterminate trusses are unified and given in
details. |
