High-strength steels (HSSs) are now used globally in different structural applications. Nevertheless, investigations on HSS elements are still rare. Herein, the shear buckling response of S690 steel plate girders with corrugated webs (CWGs) is explored. This is based on virtual tests, generated by finite element (FE) modelling, that well simulate their actual behaviour. Accordingly, S690 material model is firstly checked from a recent test campaign by Sun et al. (2019). Then, the FE models are verified through comparisons with the available tests on HSS CWGs conducted by Driver et al. (2006). Based on the successful validation, virtual testing, by using the software Abaqus, is currently generated to examine the effects of the geometrical characteristics of the cross-section (in terms of the thickness (t_w) and the height (h_w) of the web). The results show that by increasing the value of t_w, the strength of the girders increase efficiently. Conversely, increasing h_w is found to increase the girder's strength, but with slightly less increase in the strength compared with the increase of the web's weight. Furthermore, the shear strengths are compared with different design models available in the literature. The design model by Leblouba et al. (2017) is found to be the best predictor for the current girders with equal fold widths. The paper extends to explore the effect of varying the design parameters of the corrugated webs on the shear response of CWGs with unequal fold widths. Accordingly, multiple virtual tests are simulated and compared to help in designing efficient corrugated webs in the future. At the end, the design model by Leblouba et al. (2017) is slightly modified by considering the effect of the fixed juncture between the rigid flanges and the web. Through this modification, the most suitable predictor for S690 CWGs is obtained with an accuracy that is not depending on the slenderness of the girder. So, it is currently recommended for design purpose of S690 CWGs with unequal fold widths.

高强度钢（HSS）现在在全球范围内用于不同的结构应用中。尽管如此，对高速钢元素的研究仍然很少。在此，探讨了带有波纹腹板（CWG）的S690钢板大梁的剪切屈曲响应。这是基于由有限元（FE）建模生成的虚拟测试，可以很好地模拟其实际行为。因此，首先由Sun等人从最近的测试活动中检查了S690材料模型。（2019）。然后，通过与Driver等人在HSS CWG上进行的可用测试进行比较，来验证FE模型。（2006）。基于成功的验证，当前使用软件Abaqus进行虚拟测试，以检查横截面的几何特征（以厚度（t _w）和网的高度（h _w）。结果表明，通过增加t _w的值，梁的强度有效地增加。相反，增加h _w发现增加梁的强度，但与腹板重量的增加相比，强度的增加略少。此外，将剪切强度与文献中可用的不同设计模型进行了比较。Leblouba等人的设计模型。（2017）被发现是折弯宽度相等的当前大梁的最佳预测指标。本文扩展以探讨改变瓦楞纸幅设计参数对折叠宽度不相等的CWG的剪切响应的影响。因此，模拟并比较了多个虚拟测试，以帮助将来设计高效的瓦楞纸幅。最后，由Leblouba等人设计的模型。考虑到刚性法兰和腹板之间固定连接的影响，对（2017）进行了稍微修改。通过此修改，获得的最适合S690 CWG的预测器的精度不取决于大梁的细长度。因此，当前建议将其用于不相等折叠宽度的S690 CWG。
