本文在等截面连续箱形梁桥剪滞效应变分法的基础上,通过对影响截面剪滞系数诸要素的分析,提出了一种以当量等截面代替变截面连续箱梁的近似计算方法,以期为变截面箱形连续梁桥的工程设计提供一种简单、有效的计算方法.
Based on the variational method of shear lag effect of continuous box girder bridge with equal cross section, this paper presents an approximate calculation method of equivalent continuous section box girder instead of equivalent section by analyzing the various factors that affect shear lag coefficient. In order to provide a simple and effective calculation method for the engineering design of continuous box girder with variable cross section.
