考虑横向碰撞效应的桥梁动力响应研究
Dynamic Response Analysis of Continuous Beam Bridges Based on Lateral Collision Effect
摘要
Abstract
The study of beam dynamic response is an important branch in the field of bridge engineer-ing,especially when considering lateral collision effects.In order to study the effect of lateral collision on the dynamic response of continuous beam bridges,an open system for earthquake engineering simulation(OpenSees)finite element software was used to build a finite element model of the entire bridge.The dy-namic response and vulnerability changes of the bridge were compared and analyzed with and without later-al collision.The results show that when the peak ground acceleration is 1.0 gal,the probability of minor and complete damage to the support is 0.97 and 0.71,respectively,without lateral collision,and 0.92 and 0.65,respectively,with lateral collision.The lateral collision effect limits the relative displacement of the support through the limiting effect of the stopper,thereby reducing the probability of damage.This has practical guidance significance for the evaluation,reinforcement,and maintenance of bridges in seismic de-sign.关键词
