| Abstract: | In this paper, the finite element method is applied to study the capability of simple supported beam with external prestressed cable and the effective width of flange. The influence of shear connection rigidity on the effective width of flange and the effect of prestress increment are analyzed. The load-carried mechanism of external prestressed composite beam with shrinkage and creep of concrete deck is also discussed. |

| Keywords: | external prestress steel-concrete composite beam effective width of flange |
