用体单元分析薄壁箱梁剪力滞效应的新方法

摘要

In order to analyze the shear lag effect of the thin-wall box section in a more accurate way,the paper points out tetrahedral body element is a more effective method,indicates that the finite element software is used to analyze the box girder modeling,and proves the accuracy of the calculation method by experiment,so as to provide certain reference for relative personnel.%为了更精确地分析薄壁箱形截面的剪力滞效应,提出了用四面体单元分析是一种比较有效的方法,利用有限元软件对箱梁建模分析,并经实例验证了本算法的准确性,可供相关人员参考。
