Strength and Behavior of Cold-Formed Steel Z-Sections Subjected to Major Axis Bending
Publication: Journal of Structural Engineering
Volume 132, Issue 10
Abstract
This paper presents a study on the strength and behavior of cold-formed steel -sections with simple and complex stiffeners subjected to major axis bending. The study involved both experimental and numerical investigations, in which a series of specimens were examined. All specimens were failed by the combined mode of shear and moment. The results from the investigations were analyzed and compared with the combined moment and shear strengths predicted by international design rules. The suitability of the design rules in predicting the combined capacity of -section with complex stiffeners was assessed through a reliability analysis.
