多跨连续梁抗震性能分析

The seismic performance analysis on multi-span continuous beam

以多跨连续梁为工程背景,进行了桥梁的抗震特性分析,在此基础上开展了非线性时程分析和隔振效果分析,并得出了一些有用的结论,对同类桥梁设计有一定的参考价值。

Taking multi-span continuous beam as the engineering background, the paper made seismic performance analysis on bridge, on this basis made nonlinear time-history analysis and vibration isolation effect analysis, and drawn some useful conclusions, had certain reference sig- nificance to similar bridge design.
