| 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. |
