CYCLIC TEST OF DIAGONAL STIFFENED STEEL PLATE SHEAR WALLS
The hysteretic behavior of thin steel plate shear walls is generally characterized by hysteretic loops that are pinched at the point of zero displacement. Traditionally, in order to avoid the pinch phenomena, more thick panels or cross stiffeners are needed. According to the angle of tensile field in panel was along the diagonal of frame, a new type of earthquake-resisting element, consisting of a thin steel plate shear wall with diagonal stiffeners, was conducted. Experimental testing were conducted on 2 one-story single bay diagonal stiffened steel plate shear walls of roughly one-third of full scale, which were subjected to gravity loads at the top of the columns and cyclic horizontal loads at the floor level. These tests provided data on general performance of the walls, which provided the basis for the investigation on initial stiffness, ductility, energy absorption capacity, load versus displacement envelope, hysteretic characteristics and deformation of the boundary frame elements etc.In this structural, diagonal stiffeners can reduce the magnitude of panel deflection, improve initial stiffness and load-carrying capacity of the structure and avoid the pinch phenomena. Good energy dissipation and displacement ductility capacity were achieved. The experimental results showed that diagonal stiffened steel plate shear wall was an effective lateral load resisting element.
