Natural Hazards Engineering Research Institute (NHERI)

The Natural Hazards Engineering Research Infrastructure (NHERI) is a nationwide, shared network of facilities made for the natural hazards engineering research community. In December 2023, the NHERI Large-High Performance Outdoor Shake Table rolled out Phase 2 of the NSF-funded Converging Design project—a three-phase initiative aimed at achieving minimal post-earthquake damage.  

Phase 1, completed in November 2023, showcased the effectiveness of post-tensioned mass timber walls and steel U-shaped energy dissipators, with Phase 2 currently integrating a gravity system with post-tensioned timber walls and Buckling-Restrained Braces. Phase 3 aims to unite a mass timber gravity frame with a resilient lateral-force resisting frame, contributing to fortifying buildings against seismic events.

Construction and testing can be monitored via the live webcam at https://nheri.ucsd.edu/live-cams. This work is part of a collaborative effort including Oregon State University, Stanford University, Colorado State University, and Penn State University with support from the National Science Foundation (#2120683, #2120692, and #2120684), USDA Agricultural Research Service, and TallWood Design Institute, along with several other industry partners.
