AbstractThe seismic design provisions of the National Building Code of Canada (NBCC) underwent significant changes between 1995 and 2005. The changes proposed for the seismic requirements of 2010 NBCC are, in comparison, limited in scope as well as in their extent. They include revisions in the seismic hazard values in the eastern region of Canada, changes in some of the site effect factors, a new minimum value for the design spectral acceleration values for concrete shear wall structures, an upper limit on the design forces as determined from a dynamic analysis and some changes related to the design of diaphragms, chords, and collectors. Adjustments have been made in some values of the higher mode effect factors and overturning moment reduction factors. Values of the overstrength and ductility related force modification factors have now been specified for two new lateral force resisting elements and structural types, namely buckling restrained braces and cold-formed structures. The present paper highlights the changes and revisions in relation to the provisions of 2005 NBCC.
