There has been extensive testing and validation of concrete precast posttensioned rocking wall systems and timber rocking walls in New Zealand and the US as it pertains to their durability to withstand a seismic event. As a result, seismic testing of the structural system of Framework focused on structural components and evaluated any deviation from the results of previous studies.
Several tests were completed at Oregon State University to validate the structural resiliency of the self-centering post-tensioned CLT rocking wall. These included a series of bare panel tests on full scale nine-ply CLT panels, crushing tests on five-ply CLT panels, and testing of three different splice methods for joining the rocking wall’s nine-ply CLT panels. This video shows the epoxy rod panel splice option which was ultimately chosen for the project.
