Abstract

Journal of Vibration and Control, Ahead of Print.
Multi-drum rocking columns (MDRC) with dry joints can rock and self-center under gravity, but negative post-rocking stiffness can produce larger displacements during strong earthquakes. This study proposes a simple stiffening system that combines a spring ...
