Abstract

Abstract

Full-size model test and nonlinear finite element analysis (FEA) are carried out to investigate the mechanical behavior and optimize the structure design of the steel-concrete composite cable-pylon anchor of Jiayue Bridge, Chongqing. The mechanical performance and load transfer mechanism of the steel-concrete composite cable-pylon anchor are studied first by the model test comparing with the nonlinear FEA. Then, the optimized structural parameters of the composite cable-pylon anchor are analyzed by FEA. Results show that the stresses of components of cable-pylon anchor are on a low level and distribute evenly. The relative slippage between anchor box and concrete pylon is small, and the maximum value is only 0.029 mm. The stiffness of shear connectors has a great impact on the principle stress of concrete pylon. When the stiffness is increased by 5 times, the principle stress of concrete pylon is reduced by 17.3%. The cable-pylon anchor’s structural design of Jiayue Bridge meet the requirement of safety and economics.
