It is often said: "The bigger they are, the harder they fall." But the largest full-scale building ever tested on the University of California San Diego's newly upgraded outdoor shake table remained upright through dozens of earthquake simulations run over several weeks. The Natural Hazards Engineering Research Infrastructure's TallWood project is a 10-story building made of cross-laminated mass timber, a load-bearing material composed of thick, compressed layers of wood. Shiling Pei, Ph.D., P.E., RSEI, M.ASCE, an associate professor of civil and environmental engineering at the Colorado School of Mines and a principal investigator on the project, says the building uses a combination of innovative design elements to resist seismic forces. |
