| Abstract: | In this paper, the stability of the large cantilever steel thin_wall box girder with several load cases during construction is analysed by means of 3_D plate_shell element method. In view of the lost stability mode, some proposals are presented with regard to the design of large cantilever steel thin_wall box girder. And the proposals may serve as good references for the bridge design with the similar structure. |
