In order to research different width-span ratio and aspect ratio on shear lag effect of double-sided box girder, the simple supported and cantilever systems are taken as research object. Simulating the shear lag effect is based on the finite element analysis software ANSYS. The conclusions of research are as follows: when width-span ratio η is 0.25∼0.5, the shear lag effect of the main beam varies the most under uniformly distributed load. With width-span ratio decreasing, the normal stress distribution tends to be more uniform. When aspect ratio decreases, the shear lag effect of double-box beam decreases gradually, but the variation amplitude is not big. Compared with aspect ratio, width-span ratio has a greater influence on the shear lag coefficient of double-sided box girder.
