【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。更多还原

【Abstract】 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 seismic response of curved girder bridge under the action of a single horizontal component and two horizontal components.Some reference for seismic design of curved beam bridge with pier girder consolidation is proposed.更多还原
