In this paper,ANSYS FEM program is used to study the lateral instability behavior caused by static—wind load of cable—stayed arch bridge.Furthermore,the parameters,including initial cable tension,towerheight,cable distance and position of cable on arch is considered in theoretical study.The results show thatcables can control buckling form effectively,and cable—stayed arch bridge has better performance of lateralwind—resistant stability.Initial cable tension,tower height can be increased,and cable distance can be re—duced to improve performance of lateral wind—resistant stability,and the effect of tower height is most extraordinary,increasing tower height ever doubled the performance of lateral wind—resistant stability nearly.Posi—tion of cable on arch has obvious effect on the performance of lateral wind—resistant stability,and cable—plane eenterline is appropriate in the quartile of arch rib.
