Abstract: Thin-walled steel tubular columns with circular cross sections are widely used as cantilever piers in bridges due to their excellent structural and constructional advantages. However, local buckling, global buckling, or ...

Abstract: This paper deals with the elastoplastic large deflection analysis of thin steel plates subjected to in-plane cyclic compression and tension using the finite element method. The modified two-surface plasticity model, recently ...

Abstract: This paper presents the nonproportional cyclic elastoplastic behavior of structural steels under biaxial loading, through a combined experimental and analytical study. In particular, the work seeks to illustrate the cyclic ...

Abstract: This paper is concerned with the analytical modeling of the cyclic behavior of structural steels. The modified uniaxial two-surface model developed by Shen et al. in 1992 is generalized to a multiaxial two-surface model, ...

Abstract: Ring stiffeners are preferably used to enhance thin-walled cylindrical shell buckling resistance while subjected to external lateral pressure. A comprehensive finite element (FE) numerical study investigated the influence ...
