RELIABILITY ANALYSIS ON THE AXIALLY-COMPRESSED MEMBER OF HIGH STRENGTH COLD-FORMED STEEL STRUCTURE

摘要：

In this paper, considering the effects of the uncertainty from strength,geometrical parameters of sections, analysis method and external loading, the second-order moment probability method is used for conducting reliability analysis of 550MPa high-strength cold-formed thin-walled steel structures, from which the reasonable design method for load-carrying capacity, targeted reliability index, and the corresponding design strength level are studied considering the material characteristics of the high strength steel. The results show that the load-carrying capacities of the axially-compressed members with high-strength cold-formed steel calculated from Chinese Technical Code of Cold-formed Thin-walled Steel Structures GB50018-2002, is well satisfied the targeted reliability index in structural design if the suggested design value of material strength according to their thickness is adopted.
