Abstract

This paper reports the results of the finite element analysis and in situ testing of a large-scale (4 m x 10 m) pneumatically isolated concrete slab. The slab was constructed as a design prototype for next-generation metrology laboratories at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. Data include computed and measured mode shapes and natural frequencies, as well as the measured performance under ambient conditions. The slab was able to achieve one-third octave band amplitudes as low as 0.25 ?m/sec (10 ?in/sec) over some frequency ranges.
