AbstractCanada's 5th Generation seismic hazard model is the basis for the seismic design provisions in the 2015 National Building Code of Canada. For the southern half of British Columbia and Alberta, the hazard contributions come from three main sources of shaking - crustal, in-slab and interface earthquakes - and this report provides their individual hazard contributions. Spectral acceleration is determined at 0.05, 0.1, 0.2, 0.3, 0.5, 1.0, 2.0, 5.0 and 10.0 second periods, peak acceleration and peak velocity. Values at eight probability levels are provided between 1/50 and 1/2,475 per annum. The spectral parameters allow the construction of uniform hazard spectra (UHS) for each of the three contributors. These individual UHS will allow better-informed choices for scenario events and for the selection of representative time histories than is possible from the total UHS.
Summary(Plain Language Summary, not published)
Canada¿s 5th Generation seismic hazard model is the basis for the seismic design requirements in the 2015 National Building Code of Canada. For the southern half of British Columbia and Alberta, hazard comes from three main sources of shaking - crustal, in-slab and interface earthquakes - and this report provides their individual hazard contributions. Earthquake shaking ground motions are determined for a range of periods, for peak acceleration and peak velocity. Values at eight probability levels are provided between 1/50 and 1/2475 per year. The calculated parameters allow one to construct uniform hazard spectra (UHS) for each of the three hazard components. These individual UHS will allow better-informed choices for hypothetical events and for the selection of representative time histories of earthquake shaking than is possible from the total UHS.
