Abstract

In this paper the behaviour of a new hysteretic dissipater for seismic passive protection of structures is analysed. The device is made in aluminium and steel and the results of a series of shaking table tests on a 3D two-floor steel frame equipped with these dissipaters are described. The device is subjected to shear forces during a seismic event and it has been designed on the basis of an optimization procedure having the objective of maximizing the energy dissipation. The experimental analysis gives a better characterization of the devices and the real quantity of the dissipated energy. The results show the values of the maximum acceleration and maximum displacements at each floor, together with the maximum interstory drifts measured on the 3D frame subjected to some earthquake records. The same measurements realized on the 3D model without dissipaters subjected to the same earthquakes give the level of the efficacy of the proposed device in reducing the seismic effects on structures.
