Static Analysis of Reinforced Concrete Arch-Deck Bridge with Archaized Connective Corridors

Abstract:

As the requirements of traffic functions and urban landscape, a reinforced concrete arch- deck bridge is designed with archaized connective corridors. The main dimensions and drawings are introduced and the static analytical results of the bridge are discussed in this paper. The numerical model was built by the integrated solution system for bridge and civil engineering- MIDAS/Civil. The results show that the temperature of bridge and the horizontal shift at arch toes due to sedimentation play important roles sensitively influencing the bending moments and displacements of control sections. Compared numerical results of the bridge only with dead loads, the maximum bending moments and displacements would reach 3.81 times and 6.52 times respectively. The axial force of arch is mainly resulted from dead loads, which gradually increases from arch crown to arch toes. The design and numerical results would give some references to similar bridges.
