Experimental Cyclic Response of a Novel Friction Connection for Seismic Retrofitting of RC Buildings with CLT Panels

The seismic vulnerability of existing RC framed buildings in seismic-prone areas requires affordable and practice-oriented solutions for their retrofitting. In this paper, the authors present a retrofitting solution based on combined use cross-laminated timber (CLT) panels asymmetric friction connections (AFCs). AFC connection is activated when force level reaches design threshold. energy dissipation increases structural capacity reduces displacement demand. This research presents outcomes an experimental campaign selected prototypes these connectors. assess dissipative from cyclic load tests four different connector arrangements examine contribution aluminum shim layers. first results highlight significant potential AFC, although they also provide evidence notable sensitivity constructive details. modeling approach to simulate results.
