Abstract: This paper summarizes computer method of seismic analysis for bridges.Confirmable method includes,elasticity static method ,static-plastic analysis,response spectrum method and time history scheme;Seismic analysis of probability includes:the random vibration and the pseudo excitations method.This paper discuss the virtue and defect about these methods.The keystone and trait of the pseudo excitations method are paticularly presented.At last we bring forward some questions needing further study.
Key words: seismic analysis for bridges, response spectrum method , time history scheme, the random vibration, the pseudo excitations method
