Experimental Seismic Response Assessment of Tall Buildings With Large Mass Damping
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper describes an experimental investigation into the seismic performance of a novel integrated damping system. The proposed damping concept mobilises a portion of the building's own mass to generate damping from its differential motion relative to the lateral load‐resisting system.
