Abstract: A multi-level seismic performance assessment is performed on a near full scale beam-column subassembly. The physical model is taken from a 3D exterior connection of a jointed precast concrete frame structure that is designed for damage avoidance. Unbonded post-tensioned prestress is provided by high-alloy high-strength thread-bars. Draped and straight tendon profiles are used in the transverse and orthogonal directions, respectively. The joint region is armoured to avoid damage by providing steel plates at the beam-column contact points. Supplemental energy dissipation is provided by high-performance lead-damping devices cast internally in each beam. Bi-directional quasi-earthquake displacement profiles are applied meaning the input displacement profiles are taken directly from the results of inelastic dynamic analysis. Three input earthquakes are selected probabilistically to represent multiple levels of seismic demand. Results from physical testing are critically discussed.
