Abstract
The structure and stress distribution of the anchorage zone on pylon of long-span cable-stayed bridge are extremely complexi¤Based on the model of concrete pylon steel-anchor-box in cable-stayed bridge, the configuration character of the anchorage zone was introducedi¤In combination with finite element method, the stress distribution features analysis and the simulation analysis of the zone were carried outi¤The results showthat (1) although th are a lot of slabs, the global behavior of steel-anchor-box is well and the cable force transfers fluently; (2) the areas of stress concentration are fairly localized; (3) the structural performance satisfies the design requirement under 1i¤7 times the design load.The results are of importance guidance to the design of anchorage zone on pylon of long cable-stayed bridgei¤
