Shear deflection is a key factor to take into consideration since members with smaller web areas are more vulnerable to shear. As a result, this work focuses on using theoretical, experimental, and analytical methods to undertake a parametric analysis to determine the shear deflection of an open web steel beam under non-uniform bending. The ABAQUS software package was used to analyse a total of sixty nonlinear finite element models, and part of the model’s behaviour was tested experimentally. The flange and web slenderness ratios that distinguish the finite element models were noted using a codal comparison. In addition to the overall behaviour, the shear deflection of various member components was calculated and compared to the shear deflection equation provided by Das and Basole and, Timoshenko and Gere. The findings indicated that load versus deflection plots could be produced analytically and experimentally, proving a good link between the two. The current work presents an appropriate adjustment factor for the theoretical shear deflection equation to compute the precise shear deflection behaviour of an open web steel beam. The accuracy of the proposed formulation is proven by an R-squared (R²) value of 0.999. Additionally, the maximum shear deflection limit for the simply supported open web steel beam under non-uniform bending was calculated as part of this study, along with the impact of the span-to-depth ratio on shear deflection. The investigation comes to the further conclusion that the parametric variation significantly affects the shear deflection.

剪切挠度是需要考虑的一个关键因素，因为腹板面积较小的构件更容易受到剪切的影响。因此，这项工作的重点是使用理论、实验和分析方法进行参数分析，以确定非均匀弯曲下空腹钢梁的剪切挠度。使用ABAQUS软件包分析了总共60个非线性有限元模型，并对模型的部分行为进行了实验测试。使用余数比较记录了区分有限元模型的翼缘和腹板长细比。除了总体行为之外，还计算了各个构件组件的剪切挠度，并将其与 Das 和 Basole 以及 Timoshenko 和 Gere 提供的剪切挠度方程进行比较。研究结果表明，可以通过分析和实验来生成载荷与挠度图，证明两者之间存在良好的联系。目前的工作为理论剪切挠度方程提出了适当的调整因子，以计算开腹钢梁的精确剪切挠度行为。R 平方 (R ² ) 值为 0.999，证明了所提出公式的准确性。此外，作为本研究的一部分，还计算了简支开腹钢梁在非均匀弯曲下的最大剪切挠度极限，以及跨高比对剪切挠度的影响。调查得出进一步的结论：参数变化显着影响剪切挠度。
