Abstract

Light-gage steel structures constituted mainly of cold-formed steel members have been widely employed in a variety metal construction in Brazil and many countries. The reduced thicknesses this elements making connection designing difficult due the occurrence of the local effects that generally govern these designs in thin elements. This paper presents and discusses the results of a experimental investigation of bolted connections in cold-formed angles (either equal or unequal legs) and channel members (1.55 to 3.75mm thickness), and an evaluation of the structural behavior of the connections with identification of the corresponding failure modes, with emphasis on the tensile capacity of angles and channels. The results are compared to those obtained based on the Supplement # 1 of the AISI/96 (1999) and Brazilian Code for the design of cold-formed steel structural members.

Structural Behavior of Bolted Connections in Cold-formed Steel Members, Emphasizing the Shear Lag Effect

Light-gage steel structures constituted mainly of cold-formed steel members have been widely employed in a variety metal construction in Brazil and many countries. The reduced thicknesses this elements making connection designing difficult due the occurrence of the local effects that generally govern these designs in thin elements. This paper presents and discusses the results of a experimental investigation of bolted connections in cold-formed angles (either equal or unequal legs) and channel members (1.55 to 3.75mm thickness), and an evaluation of the structural behavior of the connections with identification of the corresponding failure modes, with emphasis on the tensile capacity of angles and channels. The results are compared to those obtained based on the Supplement # 1 of the AISI/96 (1999) and Brazilian Code for the design of cold-formed steel structural members.
