This paper deals with the shrinkage behavior in steel-concrete double composite continuous box girder bridge, which has two concrete slabs at upper and lower surfaces of the steel box girder in the region of the intermediate supports only. First of all, the relationship between stress and strain in concrete for analyzing the shrinkage behavior and the solution for shrinkage are presented. Next, a three spans continuous double composite box girder bridge is selected as the analytical model and its numerical analysis is carried out. Also, the test results used comparative large scale model are reported. Finally, the comparison between analytical and test results is presented and discussed herein.
