Abstract

In-situ testing of a lively floor is necessary for the design of an effective remedy. The ideal evaluation is to use full experimental modal analysis, which requires substantial equipment including at least one floor shaker, to fully define the natural modes of the floor system; however, it may not be possible, at least for an initial evaluation, because of cost. An alternate testing procedure is to use a handheld spectrum analyzer with heel-drop and timed walking excitations. This paper describes the procedure and compares results with experimental modal analysis techniques. The method is further evaluated with results from a laboratory floor and an occupied building. The method is shown to be economical, convenient and effective.
