摘要
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.
This paper Presents an approximate method to calculate the shear lag in variable cross section continuous box girders by substituting equivalent uniform section for variable cross-section. Thus, it offers a simple and effective calculating method for the design of continuous box girder bridge with variable cross-section.
