摘　　要：向量式结构力学是基于向量力学提出的广义而系统化的结构数值分析理论,特别适合求解非线性、大变形及不连续问题。本文基于向量式结构力学基本原理建立了桁架结构非线性静力分析方法,给出详细的计算公式和计算步骤。给出三个数值算例,通过与ANSYS计算结果的对比分析,验证了向量式结构力学对非线性静力分析的适用性和精度。Vector mechanics of structure is a generalized and systematic numerical theory for structural analysis based on vector mechanics.It is especially suitable for problems characterized by nonlinear,large deformation and discontinuity.The nonlinear static analysis method for truss structures was developed based on the basic principles of vector mechanics of structure in this paper.And the detailed computation formula and steps are provided.Three numerical examples are provided and analyzed by the proposed method.By comparing with the results of ANSYS software,the applicability and accuracy of the vector mechanics of structure for nonlinear static analysis of truss structures are validated.
