桥梁结构地震作用破坏准则的探讨

The exploration on the failure criterion of the bridge structure with the influence of earthquake effects

针对目前国内外学者提出的众多桥梁结构地震破坏准则进行了综述,并对各种破坏准则的优缺点进行了比较,指出确定一个合理的破坏准则是减轻地震损失最有效的方法,以期最大限度地减小地震损失。

Aiming at the failure criterion of the bridge structure with the influence of earthquake, exclaimed by many experts at home and abroad, the paper gives the general introduction on this aspect, compares the advantages and disadvantages of all kinds of failure criterion, and points out that the most efficient way to reduce the disaster＇ s effects is to ensure a reasonable failure criterion in order to minimize the earthquake losses.
