Seismic response analysis under longitudinal and lateral excitation of rigid frame bridge subjected to near-fault pulse-like ground motions

摘要: With the near-fault and far-fault pulse-like ground motions recorded by four stations, seismic response of reinforced concrete long-span rigid frame bridges subjected to under longitudinal lateral excitation is studied. And comparison next conducted with bridge in same sites. The features two kinds are analysed. results show that more significant than non-pulse-like peak acceleration. advice given on design area.
