摘要
以深圳市某互通立交匝道桥工程为背景,针对曲线梁桥地震响应的复杂性,运用大型结构分析程序Midas/Civil建立空间有限元模型,采用动态时程法对其进行地震响应分析,研究水平地震动单向输入、双向输入时墩梁固结曲线梁桥的地震响应差异,提出墩梁固结曲线梁桥抗震设计要点。
Based on an interchange ramp project in Shenzhen, a finite element model is built by using large scale structural analysis program Midas/ Civil, in view of the complexity of seismic response to curved beam bridge. The dynamic time history analysis method is used to study the difference of seis- mic response of curved girder bridge under the action of a single horizontal component and two hori- zontal components. Some reference for seismic design of curved beam bridge with pier girder consoli- dation is proposed.
