The new buckling curves for cold-formed stainless steel equal-leg angle columns

The design rules for centrically compressed stainless steel equal-leg angle members are not explicitly stated in the current European standard SRPS EN 1993-1-4. This paper summarizes results of extensive research conducted on this type structural elements aiming to define recommendations their design. Based a systematic experimental investigation, detailed numerical analysis was performed, and database columns' resistances were defined. Material geometric nonlinear included three key alloys, austenitic, ferritic duplex. curves flexural flexural-torsional buckling check have been proposed accordance with codified procedures.
