Novel self-centering friction damping system for seismic resistant cross laminated timber structures

Latest research findings have shown that CLT buildingsconstructed with traditional connections such asnailplates or bolts can experience high damage duringand after a severe earthquake. In this paper a newtype of low damage CLT wall system with innovativeresilient slip friction (RSF) joints is introduced.The component test results in conjunction withnumerical cyclic analyses demonstrate the capacityof this system for dissipating seismic energy as wellas self-centring behaviour. The numerical time-history seismic analyses on a core system with RSFconnections exhibited the efficiency of the proposedsystem in terms of ductility, energy dissipation andself-centring behaviour as key factors for providing alow damage seismic design.
