Shear strength and stiffness enhancement of cross‑stiffened steel plate shear walls
Subject Areas : Structural Mechanics
Abstract :
AbstractNowadays, the use of steel plate shear walls, as an effective seismic resisting system, has been of great interest in enhancingthe lateral strength and stiffness of buildings both in renovation and seismic rehabilitation of existing concrete and steelstructures. In the present research, the shear strength and stiffness of steel plate shear walls in various configurations ofstiffeners, including horizontal, vertical, and horizontal–vertical, were investigated by finite element method and finallysemi-empirical relations were presented in this regard. The results indicated that the shear strength and stiffness of stiffenedSPSWs were well predicted by the proposed relations, but increasing the number of stiffeners above a certain range will nothave a significant effect on enhancing the stiffness and strength.Keywords
