Abstract

The aim of this study is to investigate the compressive buckling behavior of non-seismically detailed gusset plates welded to a column only and to predict their stress distribution through experiments and finite element analyses. Two gusset plate configurations were selected as specimens and finite element models, and it was experimentally verified that the compression strengths equations proposed in previous studies overestimate the compression strengths of gusset plates. The finite element analysis results revealed that gusset plates welded to a column only are subjected to both compression forces and bending moments due to eccentricity between the center of the weld surface, resulting in an approximately bi-linear stress distribution that approaches the tensile yield and buckling stress at the edges of a gusset plate. Based on the buckling shapes obtained from finite element analysis, it is assumed that the effective length factor for the free edge subjected to compression is close to 1.
