The innovative control strategy of seismic response of buildings “Base Dissipation” (BD) is herein described and analysed. The new control strategy leads to dissipate seismic energy at base of a building through the decoupling of the motion of the superstructure from the soil one through an appropriate damping hinge interface.
To investigate the proposed strategy, a non-classical damped system is analyzed by an innovative mathematical formulation in the state space by considering a 2DOF system, being the superstructure described by the first mode shape. Modal and numerical analyses lead to identifying optimal design parameters and allowing for preliminary investigation of the robustness of the new BD control strategy.
