Cold-formed Hollow Steel Sections (HSS) are widely
used in the construction industry. These members are perforated
for various reasons, such as ductwork, connection to other
members, creating aesthetic form, geometric optimization to
produce lightweight structural members, and accommodation of
many services like plumbing, electrical cables, wires, heating, etc.
However, the existence of the perforations is likely to impact the
structural stability and performance of columns. Therefore, finite
element analysis (FEA) was performed in this study to examine
the load-carrying capacities and behaviors of perforated coldformed square hollow steel stub columns under axial and
eccentric compression loading. The perforations have a circular
form located at column mid-height and, the diameter of
perforation to cross-section width ratio was constant in all models
with the value of 0.44. In addition, to investigate the eccentricity
of the circular perforations, stub columns were modeled with the
ratio of the transverse displacement of the circular perforation to
the section width was 0.20, and both axial and eccentric
compression loading was applied separately. The analysis results
showed that the most critical case occurred when the circular
perforation and the eccentricity of the compression load were on
the same side.
