Many studies in literature proved the excellent hysteretic behaviour of metal shear panels that exhibited large ductility and energy dissipation capacity under cyclic loading. The lack of standardized design procedures has seriously limited their use for seismic retrofitting of RC buildings. This paper develops a passive control design method for RC structures added with metal shear panels. The simplified method is based on a single-degree-of-freedom idealization and an optimum equivalent stiffness distribution to arrange the metal shear panels over the height of the building. The design method is validated through implementation in two different building cases. Its effectiveness is demonstrated through nonlinear dynamic analyses focusing on the effects of the cyclic behaviour of the metal shear panels.

Abstract
Many studies in literature proved the excellent hysteretic behaviour of metal shear panels that exhibited large ductility and energy dissipation capacity un-der cyclic loading. The lack of standardized design procedures has seriously limited their use for seismic retrofitting of RC buildings. This paper develops a passive control design method for RC structures added with metal shear panels. The simplified method is based on a single-degree-of-freedom ideali-zation and an optimum equivalent stiffness distribution to arrange the metal shear panels over the height of the building. The design method is validated through implementation in two different building cases. Its effectiveness is demonstrated through nonlinear dynamic analyses focusing on the effects of the cyclic behaviour of the metal shear panels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
