ABSTRACT:

Built-up cold-formed steel elements are efficient structural elements, very attractive due to material savings, but also for ease of construction. The connection between the built-up beam components can be easily obtained by screws, but the developments in the welding process also led to other solutions like spot welding. The WELLFORMED research project, conducted within the CEMSIG Research Center of the Politehnica University of Timisoara, proposes to study a new technological solution for built-up beams made of corrugated steel sheets for the web and thin-walled cold-formed steel profiles for the flanges, connected by spot welding. Within the research project, the experimental work includes tensile-shear tests on the lap joint welded specimens, were different combinations of steel sheets with various thicknesses were tested and, tests on two full-scale beams in bending. The paper presents the results of the experimental tests, both on lap joint specimens and on the full-scale beams. A numerical model that replicates both the beam instabilities and the force-displacement response of the beam is presented.
