基于有限元分析的双曲拱桥结构承载能力检算

Carrying Capaeity Evaluation of Hyperbolic Arch Bridge Based on Finite Element

老旧桥梁的健康状况评定关系到交通运输安全,在不宜进行荷载试验的情况下,结构检算是一种较有效的评定方法。通过有限元软件分析双曲拱桥在不同效应组合下的受力状态,对承载能力极限状态和正常使用极限状态下的安全状况进行检算,实现对桥梁承载能力的有效评定。

The health evaluation of old bridge relates to transportation safety, in the case of load test is not suitable, structural calculations is a kind of more effective assessment method. By analying the stress state under the combination of different effects through the finite element software, the situation of the safety under the bearing capacity limit state and serviceability limit state is checked, carrying capacity of the bridge is implemented.
