Abstract

In this work, the problem of wave propagation in a smart building, Virginia Tech’s Goodwin Hall, is investigated. Goodwin Hall is a five-story, L-shaped engineering building that is instrumented with 225 accelerometers. The accelerometers are permanently mounted on the building’s steel columns and girders allowing for a continuous monitoring of vibration activities. Using the building’s accelerometers, the propagation of elastic waves emitted from a series of floor impact excitations is studied. Wave propagation within a given floor as well as floor-column interaction are investigated in this study. Experimental results suggest that waves of the first anti-symmetric mode are induced in the floor due to impact excitation. Wave mode conversion takes place at the floor-column interface, and the waves propagating along the column are found to be of the first symmetric mode. Time-of-arrival-based calculations are implemented to obtain an estimate of wave speed in the building’s components and the limitations of this approach are discussed.
