1C: Seismically Resilient Tall Wood Building Systems

Metropolitan Ballroom
Topic Area

Climate, Multi-hazard Modeling, and Earthquake Resilience


As a new construction type recognized in the most recent International Building Code, tall wood buildings are attracting intense interest from architects, engineers, and investors around the world. Combined with innovative low-damage lateral system and non-structural components, tall wood buildings are promising resilient solutions for regions with high seismicity. In order to provide such solutions, a series of full-scale buildings were designed, analyzed and tested recently on the six-degree of freedom NHERI Large High Performance Outdoor Shake Table (LHPOST6) at the University of California, San Diego. The tests included a 10-story mass timber building and a 6-story mass timber building realized by removing the top four stories of the 10-story structure. These test buildings included a variety of resilient lateral systems including (1) post-tensioned mass timber rocking walls, (2) post-tensioned lateral system with buckling-restrained boundary elements, and (3) innovative steel braced-frames. The buildings were designed using code-alternative performance-based designed procedures for a site in Seattle, WA. The test buildings also included non-structural walls and façade, resilient modular stair systems, and fire sprinklers. With the newly upgraded LHPOST6, the building systems were subjected to over 200 ground motions of varying intensity up to the Maximum Considered Earthquake shaking for the design location, including with 1-D, 2-D, and 3-D motions, and using crustal and subduction zone earthquake recordings. The design, modeling, testing, and initial results from these tests will be introduced in this session.
