     the configuration and mechanical behavior of steel-concrete composite cable-pylon anchorage in cable-stayed bridges are very complex. considerable local deformation of composite cable-pylon anchorage zone could occur under the horizontal component of the inclined cable force. it is difficult and unfeasible to analyze the horizontal mechanical behavior of the composite cable-pylon anchorage by the traditional analytical theory of composite structures. in this paper, full-scale model tests were carried out according to an actual project to analyze the horizontal mechanical behavior of composite cable-pylon anchorage. stress distribution patterns of the main members and the failure modes were obtained. structural response of the anchorage was analyzed by spatial solid and shell finite element model. by analyzing and simplifying the configuration and details of the structure, the expression for calculating the horizontal force burdened by the main members of composite cable-pylon was derived based on the deformation compatibility principle. the equation for calculating internal forces of the main members in the composite cable-pylon anchorage was also obtained. it is shown that the proposed simplified method agree well with the experimental result and finite element method result.
