AbstractSeismic hazard design values are estimated for 161 Canadian Missions abroad. The method is broadly based on applying spectral shape and magnification factors to move from the 10%-in-50-year Peak horizontal Ground Acceleration (PGA) values given by the Global Seismic Hazard Assessment Program (GSHAP) to the 2%-in-50-year PGA and spectral acceleration values desired. Four sets of factors were derived from Canadian seismic hazard results for Continental Low Seismicity, Continental Moderate Seismicity, Plate Margin, and Plate Boundary tectonic environments. The resulting design spectra are intended to be a) used for screening studies to assess the relative need for remedial work; b) used for Rapid Visual Screening (FEMA 154); and c) applied in the context of the National Building Code of Canada, in conjunction with local hazard maps and national building codes, in order to deliver appropriate safety to the Missions and continuity of consular services.
