摘要
建立了三种空间杆系计算模型,按地震安全性评价报告给出的场地设计规准反应谱,分别计算了宿迁南互通匝道桥主跨的地震反应,对三种模型的计算结果进行了对比分析,指出了9度强震作用下三墩共同作用的重要性。
Three type of 3D beam calculating models are established.The main span of Suqian south interchange ramp bridge is analyzed according to spectrum given by the earthquake safety evaluation report.Comparison analysis on results of three models shows that it is important for the bridge with its three piers work together simultaneously under 9 degree earthquake.
