A pretensioned bridge column system has been developed that accelerates on-site construction activities, minimizes residual displacements even after large seismic events and reduces post-earthquake damage. The connections are the key to the system’s seismic performance. They were tested under quasi-static conditions and found to perform exceptionally well with nearly zero strength degradation and
