Abstract: As urban densification occurs in regions of high seismicity, there is a demand for tall buildings that are seismically resilient, economically viable, and have less negative environmental impact. In urban regions on the west coast of the U.S., specifically the Pacific Northwest, there is significant interest in utilizing cross laminated timber (CLT) in 8- to 20-story residential and commercial buildings that are locally sourced, sustainable, and economically competitive building material. This presentation will introduce preliminary results from the NEES-CLT Planning Project that concludes September 2015, which is aimed at developing and testing CLT lateral systems that may be implemented in future tall CLT buildings in regions with large lateral loading. A series of tests, including two types of CLT lateral systems, were performed at Washington State University's Composite Materials and Engineering Laboratory, including a self-centering rocking wall system and a deformable floor diaphragm system. Numerical models for both systems were also developed to study the sensitivity of system performance to design parameters. The project team is in process of refining the analysis and the design approach and is proposing full-scale experimental validation of the tall resilient timber building concept in high seismic regions.
