摘要：In this paper, a two-span-32m-simply supported girder bridge is studied. The Anti-seismic experiments are conducted for two groups of two-span bridges of low pier and middle pier based on a bridge model, 1/7 large of the real bridge established by principle of similitude. The impacts of three different seismic oscillations on the seismic response(displacement of bearings, internal force of piers and etc.) of simply supported beams of ordinary spherical bearings and FPBs under 7,8 and 9 intensities are discussed. The damage under different seismic oscillations are made clear and the study shows that FPBs boast of good Anti-seismic performance under near seismic oscillations of different levels and are more suitable for low pier structures.
