NEESR-GC: Simulation of the Seismic Performance of Nonstructural Systems

Seismic performance of suspended ceiling systems

Part of the overall research project on Simulation of the Seismic Performance of Nonstructural Systems lead by the University of Nevada Reno, the University at Buffalo team of this NSF Sponsored Grand Challenge project (NEESR-GC) on studies of non-structural components is conducting a testing series of suspended ceilings and associated components (lighting, etc) using full size 20x50 ft (6x16 m) and 20x20 ft (6x6 m) frames, completed in Fall 2011 using the tandem shake tables at SEESL (University at Buffalo).

Preliminary Test Results

The testing was completed October 18, 2011 and here are preliminary results of testing with 1D, 2D and 3D motions

  • from floor recorded motions in Northridge, CA (1994)
  • simulated random motions compatible to AC-156 (2010) required spectra
  • simulated sine seep motions modulated to AC-156 (2010) required spectra
  • investigative motions (white noise, impulse, etc)
