Hysteretic Dissipators Made Of Aluminium And Steel: Optimal Design And Preliminary Characterization Tests

Abstract

In this paper the optimal design of a dissipator made of aluminium and steel and principally<br />subjected to shear forces and the preliminary results of the characterization tests are described.<br />The device has been designed on the basis of an optimization procedure with the objective to<br />maximize the energy dissipated in the device. The response of a 3D frame equipped with the<br />device and subjected to 7 earthquakes compatible with the response spectrum of Eurocode 8 is<br />shown. The optimal response obtained from the characterization tests exhibits a good<br />dissipative behavior of the device, highlighted by a wide enough hysteresis cycle.
