Abstract
A unique series of nine cyclic tests were performed on energy dissipating O-connectors for use in seismic resisting unbonded post-tensioned rocking wall systems. The effect of the O-connector profile, steel material and welding process for attaching the O-connectors was investigated and two different failure mechanisms were identified. The welding process used to install the O-connector was found to significantly influence the type of failure mechanism and ductility as such a new O-connector profile was developed to overcome this sensitivity. Design equations to estimate the ultimate strength of the O-connector were proposed and used to develop a bilinear force-displacement approximation.
