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.
