桥墩形式对曲线形连续刚构桥地震响应的影响
The influence of pier types on the seismic response of the curved continuous rigid frame bridge
摘要
Abstract
Regarded Xiniu Bridge as the background,the main piers were designed to be single-col-umn thin-wall piers,double column type thin-wall piers and combined type piers respectively.U-sing Midas/Civil,this paper made a three-dimensional seismic time-history analysis for high-piers long-span curved continuous rigid frame bridge,compared and analyzed the seismic performances in different pier types and curvature radius.The results show that,in girder bending moment dis-tribution,the bridge in double column type performed better than combined type.As to girder dis-placement and axial force in pier-top,the combined type had an obvious advantage.When the cur-vature radius grow in a certain pier type,the bending moment and vertical displacement in mid-span decrease evidently at first,then become flat.关键词
