Analysis on the force influence of near fault earthquake to high-low pier continuous rigid frame bridge

Jiang Nan;Liu Peng;China Railway Eryuan Chongqing Survey & Design Institute Limited Liability Company;China Railway Eryuan Engineering Group Limited Liability Company;  
Taking the three span continuous rigid frame bridge as an example,through the analysis model establishment,this paper the high pier respectively were 30 m + 45 m and 30 m + 60 m two cases,the seismic response and bridge piers damage situation of bridge,the results showed that displacement time histories of high pier not consistent with low pier,made the beam body had certain reverse,the low pier top bear greater bending moment,pier bottom bear greater shear,caused the low pier damage distributed in bridge pier top,transverse beam and pier bottom interface,but the high pier damage mainly distributed in lower part.
