| Abstract: | A simplified analysis model for long span truss concrete filled steel tubular arch bridges is presented. The formula of reduction coefficient for calculating bending stiffness of the truss arch is derived. The mechanic behavior of a truss concrete filled steel tubular arch bridge in construction is analyzed. The calculated results obtained from the simplified model are in good agreement with those from the truss-model. The reliability and wide applicability of proposed method are also verified by the examples. |
