Abstract: In this paper two forms of steel pulling cable systems are discussed:the single suspend cable system and the cable truss. Few discussions have been posed of the single suspend cable system at present, and some views about this system are put forward in this article. Static analysis about the steel pulling cable system is processed and assumptions are presented. This article analyseds several factors influencing resisting wind property, such as the form of structure, the cross section of the cable,and the prestress. The function of the prestress influencing resisting wind property in different steel cable systems is firstly raised. At the same time the method of separating prestress from the tress as a result of strain isspoken. The experiment of real elements of the stainless steel cable truss shows that the tested figures are just confined with the calculated ones.
