Through collaboration with the NHERI TallWood Project funded by the National Science Foundation,an alternative non-prestressed cross-laminated timber rocking wall system with replaceable fuse components was developed by Katerra engineers and tested at the outdoor shake table at the University of California San Diego. The objective of this specific design and testing is to prove a concept for a new high performance seismic lateral system that is easy to modularize and install, and can be rapidly repaired after major earthquakes. This paper presents the results from a total of thirteen tests conducted on the proposed system, including several repairs after major shaking. The test results showed that the structural system was damage-free under service level ground motions, and experienced repairable damage at designated connection locations for design basis earthquakes and maximum considered earthquakes. Overall the system was able to limit residual drift to an acceptable level and provide a high load displacement capacity for the building system.
