摘要
以城市某桥梁工程中大跨径盖梁设计为例,分析了盖梁与立柱线刚度比值对结构内力分配的影响,采用两种不同的有限元计算软件对该大跨径盖梁进行计算比较,结构建模时考虑了桩基刚度的影响,有关内容可供类似桥梁设计时参考。
Taking the design of long-span capping beam in an urban bridge project as an example,the article analyzes the influence of the capping beam and the stud linear rigidity ratio on the inner force distribution of structure and adopts two different kinds of the finite element calculation software to calculate and compare the long-span capping beam.The influence of pile base rigidity should be considered during building up the structural model.The relative contents can be referred for the design of the similar bridges.
