Analysis on Shear Lag Effect of Single Box and Double Cell Box Girders for Wei River Grand Bridge

Abstract:

In order to study the influence of shear lag effect of single box and double cell box girder on structure，to make the rigid frame continuous bridge of Wei River grand bridge as the research object, through the establishment of finite element model, the normal stress and shear lag coefficient of the control sections in various working conditions is calculated, and the distribution of the box girder normal stress under shear lag effect is obtained.
