The current study experimentally and numerically investigated the ultimate shear loading capacity (USLC) of sinusoidal corrugated web beams (CBWs). The aim of the study was to numerically evaluate USLC for comprehensive practical dimensions of CWBs. In order to validate the numerical simulation strategy, a series of experimental tests on nine girders is performed. A comprehensive parametric study using the nonlinear finite element method then is performed for 160 cases and the effects of various parameters are discussed. The selected dimensions for numerical cases cover the typical range of steel girders in practice. A formula based on the division of areas of the shear buckling modes of sinusoidal CBWs is suggested. The numerical parameters of the proposed relation, representing the web boundary conditions and inelastic effects on shear buckling capacity, are fitted using the parametric study results. The relation was able to predict the UPLC of the numerical cases with an average difference of 10%, which is satisfactory in practice.
•An analytical formula is developed for Inelastic Shear Capacity (SC) of Corrugated Web Beams.•Effects of the web boundary and inelastic behavior on SC are well clarified.•Average error of prediction of proposed relation is less than 8% which is satisfactory.•Eurocode prediction is in safe side for SC of sinusoidal CWB.•Eurocode prediction for local buckling is better than global buckling.
