Experimental study on the axial behavior of perforated cold-formed steel wall frames

This paper presents a full-scale experimental investigation on perforated cold-formed wall frames under axial compression load. The focus of this investigation is to study the axial buckling behavior as well as to obtain the axial load capacity of the wall frames. The wall frames specimens are divid...
