A state-of-the-art review of seismic analysis of subway structure
Abstract
Firstly review the seismic damage phenomena of subway structures in history,especially focus on the seismic damage mechanism of Japanese Dakai station which heavy damaged during the great Hanshin earthquake.And than briefly summarize the major methods of seismic response analysis in recently,including static method,BART method,the method of response displacement,and dynamic finite element method,and so on.Summarize the numerical modeling research method status of subway structures under uniform seismic excitation,the research method status of subway structures considering the spatial variation of earthquake ground motion,and summarize the research status of input methods of non-uniform seismic wave and artificial boundary.And at last,briefly summarize the shaking table test research of subway structures,including the general shaking table test and the centrifuge shaking table test and the special shaking table test for non-uniform seismic excitation.In the end,give out some advice about further seismic research of subway structures.
