吊杆拱桥拱肋与吊杆线形偏位对承载能力影响研究

Study on arch rib and suspender divation impact on bearing capacity of arch bridge

通过有限元模拟与试验相结合的方法,分析研究了吊杆拱桥拱肋线形偏差、拱座位移以及吊杆偏位弯曲等病害对结构承载能力的影响,并根据相关规范得出其对结构安全性影响的定量评价。

The paper presents an analysis of the influence of arch rib alignment deviation,skewback displacement and suspender curving disease on the bearing capacity is identified by FEM simulation and experiment,meanwhile,drawing quantitative conclusions of the influence degree on arch bridge structure according to the codes.
