Live Fire Test at Shopping Mall Examines Structural Vibrations to Predict Structural Collapse

As part of its Research on Structural Collapse Prediction Technology project initiative, USFA and fire engineers from the National Institute of Standards and Technology (NIST) and Harvey Mudd College (Claremont, California) tested the ability of highly sensitive motion detectors to detect pre-collapse building vibrations from May 8-10, 2002, at an abandoned shopping mall in Woodbridge, Virginia. Vibration sensors that give early warning to building collapse could provide firefighters time to escape. These controlled fire tests examined the vibration characteristics of lightweight steel frame building construction, during fires large enough to cause collapse of steel deck roofs.Under USFA ...
