摘要：

In this paper, a comprehensive numerical study is performed with the aim to investigate the buckling and the post-buckling behavior of simply supported cylindrically curved steel panels subjected to pure shear. The main objective is to understand the influence of geometrical parameters, such as curvature and aspect ratio, on the elastic critical load and the ultimate shear resistance. Moreover, a new set of formulae are proposed, which enable simple and accurate prediction of the shear buckling coefficient and the ultimate shear reduction factor for curved panels with curvature parameter and aspect ratio within the ranges of practical interest. The proposed formulae have a form similar to the one available in EN 1993-1-5 (2006) for the prediction of the ultimate shear load of a flat panel.
