基于能量变分法的连续槽型梁桥剪力滞效应分析
Anslysis of Continous U-Shaped Girder' s Shear Lag Effect Based on the Principle of Energy
摘要
Abstract
In the paper, Resisner E' s method was adopted to build the governing equation of shear lag effect in continuous U-shape girder. The results of shear lag ratio of a (40 +64 + 40) m railway continuous U-shaped girder in an actual bridge obtained by using the finite elements method were compared with those by using the analytical method. At the same time, the effective width of the girder was also calculated. The computational formula and distribution law of shear lag effect offered in this paper can be referenced for the design and research of the same style bridges in the future.关键词
