On the Use of GB50018 and AISI Specifications to Estimate the Load-Carrying Capacity of Cold-Formed Steel Lipped Channel Columns

Abstract:

This paper addresses the applicability of the provisions of Chinese (GB50018-2002, effective width method) and the AISI Specifications (AISI-DSM, direct strength method) to estimate the load-carrying capacity of cold-formed steel lipped channel columns. It is worth noting that GB50018-2002 and AISI-DSM adopt different approaches to perform this task: while the former is based on the “Effective Width” concept, the latter may adopt the ‘‘Direct Strength Method’’. First, the relevant aspects related to the experimental investigations are briefly presented. Then, an extensive numerical study is performed by them, the estimates provided by them are compared with the experimental values. On the basis of these comparisons, some concluding remarks are drawn concerning the application of the GB50018-2002 and AISI-DSM design approaches.
