| Abstract: | 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. |
