EXPERIMENTAL STUDY OF THE BEHAVIOUR OF COLD-FORMED STEEL SECTIONS WITH PUNCHED WEBS.

Cold-formed steel structural members with punched webs and flanges are widely used in buildings. Due to lack of research results on the behaviour of such members, present design codes do not provide any guidelines for design of members with openings. In order to study the behaviour of such members stub columns with punched webs were tested. This paper summarizes the experimental findings. Local buckling load, ultimate load, load-axial …
