Open file ; 8308 Includes bibliographical references. “To mitigate seismic risk, it is important to obtain a structure’s natural frequencies and resonant amplification spectra. To this effect, ambient seismic noise data were collected at three sites of interest as well as two reference sites within the west wing of East Block on Parliament Hill in Ottawa, Canada due to the importance and historic value of these heritage buildings. The data were processed using the standard spectral ratio (SSR) and horizontal-to-vertical spectral ratio (HVSR) techniques. An ambient noise survey such as the one performed in this work is a low-cost approach for documenting the dominant dynamic properties of a structure in the linear domain”--Abstract, p. 4. gccst Seismology East Block (Parliament Buildings, Ottawa, Ont.)
