Topic:

Earthquake and Post-Earthquake Fire Testing of a Full-scale 5-story Building outfitted with Nonstructural Components on the World’s Largest Outdoor Shake Table

Speaker:

Prof. Tara Hutchinson
Tara Hutchinson is a Professor in the Department of Structural Engineering at the University of California, San Diego with research interests in the area of earthquake engineering, with particular activity in the area of large scale seismic testing. She is the principal investigator of this unique $5M multi-University, academic-industry-government collaborative effort.

Abstract:

Earthquakes and post-earthquake fires have demonstrated extensive losses, both monetary and humanitarian, in past earthquakes. Much of this has been due to the reduced integrity of nonstructural components and systems (NCSs) housed in buildings. Yet, remarkably until recently, very little research has been conducted to investigate the performance of NCSs during earthquakes and particularly considering fire following earthquake scenarios. In this presentation, the recent testing of a full-scale five-story building furnished with a broad array of nonstructural components and systems will be described. The test building incorporates, among other things, a functioning passenger elevator, stairs, a complete exterior facade, interior partition walls, piping, HVAC, ceiling, sprinklers, building contents, as well as passive and active fire systems. The building-NCS system is first supported on high rubber damping isolators, and following a suite of earthquake motions it is lifted and subsequently fixed to the shake table platen, in an effort to demonstrate the effectiveness of isolation technology in protecting the NCSs and preserving the buildings functionality. Finally, live fire tests are performed in select compartments with reduced integrity due to the prior seismic motions. Data obtained from this program will be used to evaluate and refine current code assumptions and computer models regarding nonstructural components and systems, and to find ways to minimize undesirable damage to NCSs during an earthquake.
