Resistance of corrugated web girders with openings in the light of FEM analysis

This paper presents a numerical analysis of the shear resistance tests of the corrugated web of SIN girders with opening. The analysis was carried out on seven models of girders with a web height of h_w = 750 and a web thickness of 2.0 mm with a static scheme of a simply supported beam. The assumed heights of opening were 1/3 and 1/2 of the web height and from one to three opening along the length of the girder. The results of the FEM analysis were compared with the results of experimental tests of girders without openings and with available calculation methods. Based on the obtained results, a method for estimating the computational critical shear strength of the wavy web of girders with the influence of a single opening and a group of openings was presented.
