Testing at E-Defense

This week – as part of the NSF-funded project “Collaborative Research: Frame-Spine System with Force-Limiting Connections for Low-Damage Seismic-Resilient Buildings” –  researchers from the University of Illinois, Lehigh University, Oregon State University, Kyoto University, Hokkaido University and E-Defense conducted full-scale building earthquake simulations on the shake table at the Hyogo Earthquake Engineering Research Center (E-Defense).  The four-story building employed a novel low-damage structural system and the building was furnished with hospital fixtures and equipment to evaluate protection of occupants and building contents.  The testing program concluded on December 17 with an earthquake simulation using an input acceleration record from the 1995 Kobe Earthquake (100% JMA Kobe video linked).  Due to the pandemic, researchers from the U.S. could not visit Japan for the tests, but with excellent communication and dedicated colleagues in Japan, the program was completed successfully!
