Abstract

The beam element, solid finite element models are established in this paper, which are studied the effects of different curvature radius to the shear lag effect in curved box girder. The analysis results show that the inner side and the outer side of the shear lag coefficient of curved box girder bridge is different, outside large inside small. With the decrease of the curvature radius, shear lag effect is more serious. When the curvature radius is larger than 300m, the shear lag coefficient is close to straight bridge, and the linear bridge calculation of shear lag coefficient does not produce larger error. Center curve box girder cross section of shear lag coefficient has nothing to do with the radius of curvature, and only relates to the type of load.
