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抗震分析中 ,从而对结构受地震惯性力大小的范围问题进行研究 ,可以看出拟势能原理和拟余能原理可分别求解结构竖向地震压力的近似上。In this paper, the quasi potential energy principle and the quasi complementary energy principle derived on the basis of variation principle are introduced. The quasi potential energy principle and the quasi complementary energy principle are employed to calculate the seismic loads of some structures. And both of these energy principles can also be employed to analyze approximately the structural seismic bound loads.
