梁桥叠合墩的延性抗震性能研究

Study of Aseismic Ductility Behavior for Laminated Girder-Bridge Pier

对“二次浇筑法”施工完成的叠合墩的抗震计算方法进行了理论分析 ,在此基础上对比了普通桥墩和叠合桥墩的承载能力、变形性能及截面曲率延性系数大小 ,说明了叠合墩的抗震性能的优越性。

In this paper the earthquake resisting property of the pier which constructed with the second order casting method on the girder bridge is analysed.Comparison between the common pier and the laminated pier is made by calculating the load carrying and deformation capacity and the section curvature ductile coefficient.The superiority of the laminated pier is shown.
