Abstract

Abstract

To study the elastic-buckling behaviors of steel plate wall with longitudinally stiffened only,the present design formulas and regulations for the design of stiffeners in steel shear walls were compared.And elastic-buckling behaviors of steel plate wall with longitudinally stiffened only were analyzed in detail with 3 D finite element methods(FEM).The effects of stiffener stiffness,stiffener number and aspect ratio of steel plate were analyzed.The research results showed that the longitudinal stiffener could increase the critical stress of steel plate wall efficiency,and the elastic shear buckling coefficient of stiffened steel plate wall was affected largely by the aspect ratio of steel plate,stiffener number and the bending stiffness of stiffener.The determination criterion of threshold stiffness and formula for stiffener were proposed.The torsional stiffness of stiffener was considered in the criterion.At last,the formula of elastic buckling coefficient for steel plate wall with longitudinally stiffened only was derived.Comparison with the numerical results showed that the accuracy of the formula was good and was superior than that of formulas in literature.
- steel plate shear wall,
- longitudinal stiffener,
