New Elastic Stability Formulas for Multiple-Stiffened Shear Panels
Publication: Journal of Structural Engineering
Volume 128, Issue 6
Abstract
This paper deals with the development of simple, yet accurate design formulas for elastic stability of finite plates, simply supported and reinforced with multiple equidistant stiffeners, under shear. Several stiffener arrangements are considered. In each case, the plate aspect ratio is varied over a practical range for stiffened plates to be used as shear-type hysteretic dampers for building and civil engineering structures. The buckling coefficients are determined by means of the elastic buckling theory, considering both symmetric and antisymmetric buckling configurations. The obtained numerical results are employed in the developments of approximate formulas for the buckling coefficient and optimum rigidity of the stiffener. The computed optimum rigidities are compared with the results available in the literature. It is apparent that all of the proposed formulas can be used precisely to fulfill the need in design of shear-type hysteretic dampers as well as general stiffened plates in shear.
