| Abstract: | Taking the deck panel of steel box girder of Sutong Bridge as the research object,the bearing capacity of the panel stiffened by U ribs is studied through 1/2.5 scale model tests.The results of the tests show that the yielding stress of the tested panel is less than the yielding strength of the material,which should be appropriately considered in the design. |
