In recent years many techniques for the seismic control of structures have been developed. Among these, metallic hysteretic devices are able to dissipate a great amount energy entering building during event, thanks stable behavior under cyclic loads that produces wide hysteresis loop. Steel shear panels examples elasto-plastic elements, which behavior. Generally such dampers known possess large energydissipation capacity relative their size; they cost-effective and protect nonstructural elements too. Moreover, may be easily installed substituted in structure. As disadvantage, this kind dissipating can only after sustain inelastic excursions. consequence ineffective vibrations produce interstory drifts smaller than yielding drift device. To overcome constraint, Rai Wallace Foti Diaferio proposed made aluminium alloys. fact, these alloys very ductile with limit lower ordinary steel. Numerical experimental researches developed on links. Nobile performed characterization shaking-table tests some showing instability phenomena problems connections The aim present note is find out optimum geometrical configuration an aluminium-steel panel order energy.
