Previous research showed that when steel beams are subjected to in-plane shear and bending, the FW has a lower shear capacity than the SBCWs. To estimate the SS of SBCWs, Abbas et al. conducted worthwhile experimental and analytical studies, mostly applying loaded to shear. SBCWs have been widely examined in terms of shear and bending strength. Second, due to web eccentricity, an extra in-plane transverse moment develops in the flange, which greatly reduces the CWBs’ flexural capacity. First, increasing the flange’s outstand length improves its slenderness, resulting in the flange developing local buckling strength earlier than an FWB. However, because of its geometric properties, CWB girders have a few weaknesses, which may be divided into two categories. Steel beams with corrugated webs (SBCWs) have thin webs and no transversal stiffeners, giving them an advantage over flat web beams (FWB) in terms of cost and weight. Furthermore, the load capabilities and stiffness of CWSBs were more greatly affected by increasing the shear span than by increasing the pure bending one. As a result, the shear span and horizontal fold length of CWSBs are key components for determining the strength and failure modes of beams. Finally, a parametric study using the verified FE model was conducted to assess the impact of shear and pure bending spans on the overall behaviour of SBCWs. Moreover, an analytical section comprised of the creation of a three-dimensional (3D) finite element model (FEM) was implemented. In addition, the experimental findings are compared to two codes, specifically DASt-Rishtlinie015 and EN. ANSYS software was used to create finite element models for the tested SBCWs using the finite element technique. Under four-point bending, three beams with shear-span-to-effective-depth-ratios ranging from 1.65 to 2.5 were examined to investigate the relationship between shear and bending spans and failure mechanisms. The impact of shear span-to-effective depth ratio and pure bending spans on the failure mechanism of SBCWs was investigated in this study. However, present design standards for SBCWs do not adequately address this issue. The shear span-to-effective depth ratio is known to modulate the shear behaviour of steel beams with corrugated webs (SBCWs).
