Elastic buckling behavior of steel trapezoidal corrugated shear walls with vertical stiffeners
Abstract This paper investigates the elastic buckling behavior of steel trapezoidal corrugated shear walls (STCSWs) with vertical stiffeners. On the basis of an orthotropic plate model, by utilizing the theorem of minimum potential energy and the Ritz method, the buckling loads of stiffened STCSWs can be precisely calculated using MATLAB. Then, a value of transition rigidity of stiffener is suggested and, hence formulas of elastic buckling coefficients of stiffened STCSWs are proposed. Finally, the verification of proposed formulas using a FE model shows that the formulas are validated and applicable in estimating the elastic buckling loads of stiffened STCSWs.
Highlights Stiffened STCSWs can be applied to multi-storey frames and high-rise buildings. Elastic buckling loads of stiffened STCSWs are precisely calculated using MATLAB. A value of transition rigidity of stiffeners is suggested. Formulas of elastic bucking coefficients of stiffened STCSWs are proposed. The applicability of the formulas is verified by a FE model.
