独塔斜拉桥抗震性能研究——以松花江大桥为例

Analysis of Earthquake-Resist on Simple-Tower Cable-Stayed Bridge——A Case of Songhuajiang Bridge

以松花江大桥为研究对象,应用空间非线性动力计算模型,采用桥梁结构空间非线性地震时程分析方法,对松花江特大桥塔、梁滑动支座的摩擦作用和弹性索作用进行了分析,并对结构的最终抗震性能进行了安全性评价.

According to the non-linear space kinetic model, using the method of non-linear time-history seismicanalysis on bridge structure, Songhuajiang Bridge＇s effect of elastic cable and sliding support are analyzed and the safety evacuation for the ultimate seismic performance of the structure is made.
