| Abstrait: |
Large span continuous rigid frame bridges often suffer continuous deflection of the middle span in the service. In this paper, the rigid frame-suspension composite bridge is proposed in which main cables and hangers are adopted to support part of the beam weight at mid-span. A 70+130+80m- span bridge was selected as the case study and its finite element model was built using the software of Midas. In comparison with continuous rigid frame bridge, the rigid frame suspension composite bridge suffers significantly lower creep deflection. As the tensile force of hanger rod increases, the upper deflection value increases. The results obtained have certain reference value for the design of such composite bridges. |
