With the rapid increment of the span of cable-stayed bridge,the length of stayed cable also increases obviously. The stayed cable is one of the principal force members of cable-stayed bridges. The stayed cable would be prone to exhibit vibration of large amplitude on the action of wind, earthquake and traffic load, so it reduces the life of stayed cable even caused destruction. The accurate analysis of both the static and dynamic is very important for the design of cables in cable-stayed bridges. So we need...
