多重梁式高位转换体系受力性能分析

由于上部建筑要求的限制,主梁转换有时不能满足要求,因此需要采用多重梁式转换。以工程实例为背景,采用两种结构分析软件,对多重梁式转换体系中转换主梁及转换次梁的受力性能进行分析。通过分析,明确了多重梁式转换结构体系的传力途径,证明了这种转换形式在低烈度地区的可行性,针对这种转换形式在工程实际中的应用提出一些建议。

Analysis on Mechanical Behaviors of Multiple Girder High Transfer System

Due to the restriction of superstructure, main girder transformation could not meet the requirments, so multiple girder transformation should be adopted. Here, being background with engineering examples, the mechanical behaviors of the main girder and secondary girder in multiple girder transfer system are analyzed by using two kinds of structural analysis softwares. According to the analysis, the force transmission route is made clear and definite, the feasibility of multiple girder transfer system in low intensity region is proved, and some suggestions are put forward for its application in engineerings.
