Abstract:
The paper describes an innovative antiseismic device based on steel elements subject to yielding. Through a peculiar geometry of the dissipators and the selection of a particular type of steel the device can grant superior performance for fatigue life and regularity of the hysteresis cycles. The paper describes the tests at reduced and full scale to assess the behaviour of the device and an important application under execution in Turkey.
