Presentation of a new method for calculating the equivalent thickness to design stiffened steel shear walls using Plate frame interaction model.
Nowadays, Steel plate shear walls have been considered as the lateral load resisting system in buildings in increasing the strength and stiffness of structures in two sections of seismic reconstruction and improvement. In this paper, the shear strength and stiffness of a stiffened steel plate shear...

| Sumario: | Nowadays, Steel plate shear walls have been considered as the lateral load resisting system in buildings in increasing the strength and stiffness of structures in two sections of seismic reconstruction and improvement. In this paper, the shear strength and stiffness of a stiffened steel plate shear walls under various stiffeners configuration horizontal, vertical and combined structures with finite element method has been studied and finally the proposed equations for determining the unstiffened equivalent thickness of the steel plate The proposed model is used to design a stiffened steel plate shear wall using the proposed equations of the plate frame interaction method. The results indicate a acceptable prediction of the capacity and stiffness of the stiffened steel shear walls using proposed equations and the error rate has been less than 15%.Nowadays, Steel plate shear walls have been considered as the lateral load resisting system in buildings in increasing the strength and stiffness of structures in two sections of seismic reconstruction and improvement.
