This report describes the development of a new testing facility for the evaluation of suspended ceilings and
other nonstructural components that can be used with single or tandem shake tables. The 20 × 50 ft test
frame was designed to simulate realistic ceiling performance correlated with the response observed during
real earthquakes. The frame has dynamic characteristics with variable frequencies to match those typicallyfound in fl oors (or roofs) with suspended ceilings. It was also designed to accommodate various structural
materials and different framing layouts. Analytical models were developed using SAP2000 to estimate the
dynamic properties and complete the design of the test frame. The combined designs of the physical frame
and the shake table motion allow for testing a variety of suspended systems while simulating realistic fl oor
motions and eliminating side effects due to wall distortions. Finally, procedures for motion design that can
be implemented in other experimental facilities are introduced.
