斜拉拱协作体系桥有限元综合算例分析

Analysis on Synthetic Examples of Finite Element of Cooperative System Bridge with Cable-stayed Arch

建立了斜拉拱协作体系桥索力优化有限元模型,采用Midas/Civi L2013有限元计算软件,对斜拉拱协作体系桥初定成桥状态进行分析,通过计算得出成桥状态的合理调整方案,对正常通行状态下支座受力进行验算,结果表明设计参数合理,满足相关规范要求。

The optimized finite element model of cable force for cooperative system bridge with cable-stayed arch is built, and the completed bridge state of the cooperative system bridge with cable-stayed arch that is initially built is analyzedby adopting Midas/CiviL2013 finite element calculation software. Through the calculation, the reasonable adjustment scheme for the completed bridge state is obtained, and the check calculation on the load- carrying capability of the support under the normal traffic state is made. The results show that the design parameters are reasonable, which can meet the requirement of relevant regulation.
