【Abstract】 In conventional aseismic designs, much attention has been paid to the study of calculation method and analysis models, while seismic input mechanism is neglected. In this paper, some methods for studying seismic input mechanism of response spectra, time domain analysis and stochastic vibration analysis in aseismic designs are summarized. These methods are introduced and evaluated, and their prospect is predicted. The purpose of this review is to provide designers with proper seismic mechanism for them to chose from.更多还原
