连续刚构箱梁桥剪力滞效应的参数分析

Parameters Analysis of Shear Lag Effect for Continuous Rigid-frame Box Girder Bridge with Single Cell

采用板壳有限元方法对连续刚构箱梁桥剪力滞效应的影响参数进行了分析研究,这些参数包括:网格密度、荷载作用方式、截面尺寸、跨径布置等。研究结果对指导这类桥梁的设计与施工具有重要的理论意义和实用价值。

The present study investigates the correlative parameters of shear lag effect for a continuous box girder by using the shell finite element method. These parameters include meshing size, loading ways, section size, lay of spans and so on. The obtained analysis results have great theoretical values and practical values for the design and construction of related bridge engineering.
