In comparison with hot‐rolled or welded I‐beams with flat webs, corrugated web beams are connected with considerable material savings and fully automated production. Assuming the same load‐bearing capacity, corrugated web beams are lighter than those with a flat web, since the corrugated web beams can often be loaded up to their plastic resistance without reinforcement of the web. The research on the load‐bearing behavior of corrugated web beams without web openings is relatively mature. However, the resistance of corrugated web beams with reinforced web openings, as they are often used in buildings for installations, has not well experimentally been investigated, yet. This paper deals with the shear resistance of corrugated web beams with reinforced square web openings. Three specimens of different geometry with two square web openings were tested. The experiments are compared with a Finite Element Analysis by Abaqus® and with an analytical model allowing simplified calculation. Both models can relatively accurately calculate the shear resistance. The experimental and numerical results show that the increase of the shear resistance of perforated corrugated web beams depends on the wall‐thickness and the steel grade of the web opening reinforcement.

They consist of a welded Isection with a thin-walled trapezoidally corrugated web and flanges made of wide flat steel. In comparison with hot-rolled or welded I-beams with flat webs, corrugated web beams offer significant material savings and are produced fully automated. Assuming the same load-bearing capacity, corrugated web beams are lighter than those with a flat web, since the corrugated web beams can often be loaded up to their plastic resistance without reinforcement of the web. Research on the loadbearing behaviour of corrugated web beams without web openings is well-established. However, the resistance of corrugated web beams with reinforced web openings, which are necessary for installations in buildings, has not been well investigated experimentally yet. This paper examines the shear force resistance of trapezoidally corrugated web beams with reinforced square web openings. Two beam-like specimens with the same geometry but differently reinforced web openings were tested. The experimental results are compared with a Finite Element Analysis using Abaqus® and with an analytical model that allows a simplified calculation. The comparison identifies how the wall thickness of the web opening reinforcement affects the shear force resistance of perforated corrugated web beams.

Generally, both influences are mainly controlled by the manufacturing process, in partic-ular the welding of the girder. This paper presents experimental investigations on four laterally unbraced welded steel girders with thin-walled I-sections, whose flange-to-web junctions are welded from one or two sides to evaluate the fabrication influence. The investigations include lateral-torsional buckling tests under combined bending and torsion loading caused by three-point bending due to an eccentric vertical single force. The geometric imperfections of the welded test girders are determined by 3D laser scanning. The test results show that the influence of the geometric imperfections and the residual stresses on the lateral-torsional buck-ling resistance is limited for the tested girders.
