Stochastic Seismic Analysis of a Cable-Stayed Bridge Using CFRP Cables

Abstract

Fiber reinforced polymer (FRP) composites have found increasingly wide applications in civil engineering due to their high strength-to-weight ratio and high corrosion resistance for last two decades. This paper presents a numerical study on the stochastic seismic analysis of a cablestayed bridge subjected to earthquake ground motion using carbon fiber reinforced polymer (CFRP) cables. Jindo Bridge is chosen and schemed using CFRP cables. The cross-sectional areas of CFRP cables are determined by the principle of either equivalent cable stiffness or equivalent cable strength. The analysis of the selected bridge is conducted and the results obtained for CFRP cables are compared with steel counterpart. The results indicate that response values obtained for CFRP cables correspond well with those of the steel cables.
