桥梁震害及抗震设计方案

Bridge Seismic Damage and Seismic Design Scheme

自然灾害是不可抗力因素,而地震作为自然灾害的重要组成部分,是致使桥梁发生破坏的主要原因。论文着重介绍了桥梁震害,基于桥梁震害的产生原因,对现有的抗震设计理论进行了分析和讨论,并对桥梁抗震的未来进行了展望,即抗震设计理论由原来侧重于强度向更加注重性能的方向转变。

Natural disasters are force majeure factors,and earthquakes,as an important part of natural disasters,are the main causes of bridge damage.This paper focuses on the introduction of bridge seismic damage,based on the causes of bridge seismic damage,the existing seismic design theory is analyzed and discussed,and the future of bridge seismic design is prospected,that is,the seismic design theory from the original focus on strength to pay more attention to the direction of performance.
