AbstractCanada's 5th Generation seismic hazard model is the basis for the seismic design provisions in the 2015 National Building Code of Canada. The 2015 code uses mean ground motion on firm soil sites for a probability of exceedance of 2% in 50 years, with the ground motion being described by seismic hazard values for eight parameters: spectral acceleration at 0.2, 0.5, 1.0, 2.0, 5.0 and 10.0 second periods, peak acceleration and peak velocity. We tabulate values of the eight parameters and for three additional spectral periods (0.05, 0.1 and 0.3 seconds) for more than 200,000 grid points over Canadian territory and surrounding areas. Values at eight probability levels are provided. The spectral parameters will allow the construction of approximate uniform hazard spectra and hazard curves for every locality in Canada, and hence provide necessary information for earthquake-resistant design.
Summary(Plain Language Summary, not published)
The Open File provides the seismic hazard values for an approximately 10 km spaced grid of points covering all of Canada. These values are proposed as the design requirements for the 2015 edition of the National Building Code of Canada. The table of values at different periods (ranging from 0.05 to 10.0 seconds) of shaking and different probability levels is the main output. Additionally, a brief summary of the method, results and maps of the seismic hazard for each of the parameters at the national building code probability of 2%/50 years is provided.
