摘要
采用空间板壳单元 ,在施工过程中的几种荷载工况作用下对大悬臂薄壁钢挑梁进行了稳定分析计算 .并针对大悬臂薄壁钢挑梁出现失稳模态 ,提出在设计中值得注意的几点建议 。
In this paper, the stability of the large cantilever steel thin_wall box girder with several load cases during construction is analysed by means of 3_D plate_shell element method. In view of the lost stability mode, some proposals are presented with regard to the design of large cantilever steel thin_wall box girder. And the proposals may serve as good references for the bridge design with the similar structure.
