Abstract

An analytical method of SRF considering MDOF effect of bridge structure was put forward. The definition and calculation method of amplification coefficient were proposed. Calculation programs were compiled to analyze various equivalent pier MDOF model of bridge through the combination of finite element software. Records from four types of soil sites were selected for nonlinear dynamic time history analysis of fixed-based model. The effect of ductility, period and the type of soil sites on amplification coefficient was is cussed. And a multi-parameter formula was suggested for fixed-based amplification coefficient.
