Abstract: Based on a polygonal line tower cablestayed bridge in Shenyang, according to mechanics characteristics of concrete polygonal line tower,the mechanics characteristic were analyzed through numerical analysis on the tower anchorage area. The results show that main tower existes serious stress concentration. After setting stiffening rib, the stress concentration coefficient decreases,and the outofplane bending of the tower is eliminated. At the same time, the vertical tensile stress appeares. Therefore, the design should increase the stiffening rib size appropriately and strengthen the vertical steel and anticracking rebar.

Key words: cablestayed bridge, prestressed concrete, polygonal line tower, finite element method, mechanics characteristics
