(2006) Performance of damage-protected beam-column joints subjected to bi-directional lateral loading. Christchurch, New Zealand: The New Zealand Concrete Industry Conference, 29-30 Sep 2006.http://hdl.handle.net/10092/3516This work will further investigate the validity of Damage Avoidance Design systems through an experimental and computational study of a 80% scale sub-assembly. A coupler system is implemented whereby high strength unbonded threaded rods running through the beams are coupled to rods within the columns. The threaded rods are post-tensioned and additional energy dissipation devices are installed. Precast and cast insitu solutions are considered. A multi-level seismic performance assessment is conducted considering three performance objectives related to occupancy and collapse prevention. Bi-directional quasi-static cyclic tests and quasi-earthquake displacement tests are performed. Critical earthquakes are selected using a probabilistic computational method. Results indicate the DAD system satisfies all performance objectives. Further design improvements are discussed.enConference Contributions - PublishedFields of Research::290000 Engineering and Technology::290800 Civil Engineering::290801 Structural engineeringFields of Research::290000 Engineering and Technology::290800 Civil Engineering::290805 Geotechnical engineering
