A theoretical formula for calculating the global shear buckling strength of curved corrugated steel webs (CSWs) under simply support conditions was derived. Their geometric parameters, namely the corrugation depth-to-web thickness ratio, web slenderness, and radius of curvature, which influence the elastic shear buckling strength, were also assessed. The computational error of the formula for the shear buckling of a curved CSW was verified to be within 2% using finite element analysis. Increasing the corrugation depth-to-web thickness ratio and decreasing web slenderness significantly reduced the elastic shear buckling strength. On the contrary, reducing the height of the web or increasing the web thickness had the opposite effect. Although the radius of curvature has little influence on the shear strength of a curved CSW, it significantly impacts the buckling mode. The results provide a theoretical reference for the design and application of curved CSW bridges.

推导出简单支撑条件下弯曲波形钢腹板(CSWs)整体剪切屈曲强度计算的理论公式。还评估了它们的几何参数，即波纹深度与腹板厚度比、腹板细长和曲率半径，这些都会影响弹性剪切屈曲强度。使用有限元分析验证了弯曲 CSW 剪切屈曲公式的计算误差在 2% 以内。增加波纹深度与腹板厚度比并降低腹板细长显着降低了弹性剪切屈曲强度。相反，降低腹板高度或增加腹板厚度会产生相反的效果。虽然曲率半径对弯曲 CSW 的剪切强度影响不大，它显着影响屈曲模式。研究结果为弯曲CSW桥梁的设计和应用提供了理论参考。
