MECHANICS PERFORMANCE OF SUPER LONG-SPAN CABLE-STAYED BRIDGES USING CFRP CABLES

摘要：

To gain understanding of the applicability of CFRP(Carbon Fiber Reinforced Polymer)cables in super long-span cable-stayed bridges, by taking a 1400 m cable-stayed bridge as example,mechanics performance including the static behavior under service load, dynamic behavior, wind stability and seismic behavior of the bridge using either steel or CFRP cables are investigated numerically and compared. The results show that viewed from the aspect of mechanics performance,the use of CFRP cables in super long-span cable-stayed bridges is feasible, and the cross-sectional areas of CFRP cables should be determined by the principle of equivalent axial stiffness.
