At NHERI UC San Diego, a full-scale, ten-story, mass-timber building rests on the platen of the world’s largest outdoor shake table. It is the NSF-funded NHERI Tallwood project. The goal of this multi-million-dollar megaproject? To understand how tall wooden structures – with carefully designed structural and non-structural elements – perform under earthquake loading.
The structure was topped off in December 2022 (shown above). The experimental shake is slated for April 2023.
The structure represents the collective effort of researchers from multiple universities, many practicing engineers and architects, construction specialists, technicians, and engineering students. As well as funding from the National Science Foundation, NHERI Tallwood could not have been possible without the many industry partners who donated significant design expertise, building materials, and construction manpower.
The 2023 NHERI Tallwood tests at UC San Diego will record 800 channels of data that researchers, engineers and builders will use to strengthen civil infrastructure and render our world more resilient.
