Abstract

Abstract: With the characteristics of fiber reinforced plastic (FRP) of high tensile strength and durability, a flexible prefabricated arch bridge system based on CFRP was developed, which is not only good at load and durability, but less construction difficulty and dangerous than traditional masonry arch bridge. For discussing the feasibility of prefabricated masonry arch bridge, the processes of loading and construction of the arch bridge were modelled via ABAQUS. The FEA model of arch bridge was verified and its failure mechanism was analyzed by comparing the result of numerical simulation and experiments. The results of FEA showed that flexible prefabricated arch bridge possessed great loading-carrying capacity and third span is the most unfavorable loading location. Furthermore, the numerical results of stress distribution of CFRP and axis deformation of flexible prefabricated arch system in different lifting programs showed that CFRP can reinforce the stability of arch bridge obviously and assembly performance is severely optimized by the No.7 lifting programs, providing a reference for the design and construction control of this kinds of flexible arch bridge.
