ABSTRACT

ABSTRACT: Stiffened shear panels are a useful tool for passive seismic protection of steel framed buildings. Different metal materials can be used, namely low yield strength steel, mild steel and aluminium. The choice of the material depends on the demand, measured in terms of strength, strain hardening and ductility on the applied panels, which is a function of seismic requirements of the whole structure that can be obtained by a global dynamic analyses. The energy dissipation capacity of shear panels derive from using appropriate reinforcing ribs to prevent shear buckling in both the elastic and plastic field. The spacing and the flexural inertia of ribs depend on the material features as well as on the required shear panel deformation capacity. A wide numerical study has been carried out aiming at providing a useful design tool. Therefore, a number of shear panels have been numerically tested, considering different materials, plate slenderness and ribs arrangement. In the current paper the results of this parametrical study are provided.
