Observations from past earthquakes suggest that rocking motion can be beneficial for buildings to survive severe ground motions. Such observations motivated the development of rocking frames that are provided with a mechanism that allows column mid-height uplift (CMU). This paper describes an experimental study on the seismic performance of the CMU mechanism accompanied by dampers. The CMU mechanism behaved as expected, exhibiting sufficient stiffness and strength in shear while permitting free uplift motion. The dampers comprising honeycomb steel sheets exhibited excellent ductility and energy dissipation capacity.
