Sažetak
Built-up corrugated web beams (CWB) represent an assembly of multiple coldformed steel components of various thicknesses connected by means of screws or welding. Recently, tests on such built-up beams have been performed within the CEMSIG Research Center of the Politehnica University of Timisoara, in which the connections between the components were made by spot welding. Following the validation of the numerical model, the paper investigates the influence of several parameters, i.e.: the thickness of the flanges, the thickness of the corrugated web, the thickness of the shear panel, the magnitude of the initial imperfections and the number and position of the spot welds. The parametric study was conducted on a beam with the same global dimensions as the tested one.
