During the 2010/2011 Canterbury (New Zealand) earthquakes damage was observed to grouted connections used for precast concrete wall panels. A series of experimental tests were subsequently performed to investigate the in-plane seismic behaviour of precast concrete walls with grouted connections. Testing comprised of nine reversed cyclic in-plane tests of full-scale precast concrete wall panels. Seven walls used grouted metal duct connections at the wall-to-foundation joint, with test variables considering panel geometry, axial load, and panel reinforcement. An additional two walls were tested with grouted sleeve wall-to-foundation connections with both a single and double layer of panel reinforcement. Test data from these nine precast wall tests is published including wall design, test setup and procedures, clean sensor data, and photos.

During the 2010/2011 Canterbury (New Zealand) earthquakes damage was observed to grouted connections used for precast concrete wall panels. A series of experimental tests were subsequently performed to investigate the in-plane seismic behaviour of precast concrete walls with grouted connections. Testing comprised of seven reversed cyclic in-plane tests of full-scale precast concrete wall panels with grouted metal duct wall-to-foundation connections. Walls with existing connection detailing were found to perform adequately when carrying low axial loads, but performance was found to be less satisfactory as the axial load and wall panel length increased. The use of new recommended detailing was observed to prevent non-ductile connection response and to improve the robustness of the reinforcement splice. Test data could be used to evaluate the seismic performance of precast concrete walls to develop seismic assessment or design procedures.

Description:
During the 2010/2011 Canterbury (New Zealand) earthquakes damage was observed to grouted connections used for precast concrete wall panels. A series of experimental tests were subsequently performed to investigate the in-plane seismic behaviour of precast concrete walls with grouted connections. The two full-scale wall panels with grout sleeve wall-to-foundation connections were subjected to reversed cyclic in-plane demands. Wall failure was characterized by a combination of connection reinforcement pulling-out from the grout sleeve connector and reinforcement fracture. Test data could be used to evaluate the seismic performance of precast concrete walls to develop seismic assessment or design procedures.
