摘要
本文介绍了利用变分原理推导的拟势能原理和拟余能原理，把拟势能原理和拟余能原理应用到结构地震临界荷载分析中，从而提出了一种计算结构地震临界荷载的新方法，同时从理论上论述了为什么利用拟势能原理和拟余能原理可以分析结构地震临界荷载的上、下限问题．
In this paper, the quasi-potential energy principle and quasi-complementary energy principle based on variation principles are introduced, and the quasi-potential energy principle and quasi-complementary energy principle are used to calculate the seismic limit loads for some structures. Especially, the reason why the quasi-potential energy principle and quasi-complementary energy principle can be used to analyze the structural limit loads is discussed. The aim of the authors is to study and formulate a new method for analyzing the structural seismic limit loads.
