Finite element modelling of the shear lag effects in an HSS welded to a gusset plate

Abstract

The behavior of a typical connection at the ends of an HSS bracing member was investigated with the finite element method. The connection is effected by means of a gusset plate welded into slots in the HSS member. The paper presents the results of the finite element analyses of 25 connections which differed in the values assigned to the three main parameters that were considered. The finite element results are compared with the provisions of CSA Standard S16.1-M89, and some adjustments to these provisions are recommended. Key words: connections, steel, shear lag, finite element, hollow section, gusset.
