斜拉桥宽幅扁平钢箱梁有效宽度的探讨

摘要

According to the broad width flat steel box girder of cable-stayed bridge,the paper researches the influence of its stress feature on the shear lag effect,and explores the necessity for considering the effective width of the flange by calculating the effective width of the flange of the main beam of some steel cable-stayed bridge,so as to provide the direction for the design of the section of the broad width flat steel box girder of cable-stayed bridge.%针对斜拉桥宽幅扁平钢箱梁,研究其受力特性对剪力滞效应的影响,通过计算某钢斜拉桥主梁翼缘的有效宽度,探讨考虑翼缘有效宽度的必要性,为斜拉桥宽幅扁平钢箱梁断面的设计提供了指导。
