桁架极限承载力非线性分析中的事件追踪分析法

An Event-to-Event Strategy for Nonlinear Analysis of the Utmost Capacity of Truss Structures

阐述了桁架极限承载力事件追踪分析法的基本概念和分析过程，分析过程中考虑到受压构件的负刚度效应对系统极限承载力的影响。并用具体算例阐述了该方法的实际应用情况。

In this thes is,the basic idea and the analysis procedure of event-to-event strategy for nonlinear analysis of the utmost capacity of truss structures are explained. The effect of negative stiffness of elements in compression is considered in the analysis process. An example is given to explain the application situation of the method.
