Abstract
The building codes in various jurisdictions, including Canada, follow a common concept in designing buildings to achieve an acceptable seismic performance. The objective underlying the concept is to ensure that the buildings designed based on code provisions should be able to resist minor earthquakes without damage, resist moderate earthquakes with some non-structural damage, and resist major earth- quakes without coliapse, but with some structural as welI as non-structural damage. Seismic provisions in the building codes have evoived over the years to achieve this goal. Existing building codes focus on the minimum lateral load for which a structure
must be designed. However, it is also necessary to include the demand and response
characteristics of a structure, in the design.
The National Building Code of Canada (NBCC) is currently undergoing a review. One of the aims of this review is to permit an explicit definition of the expected seismic performance of buildings designed according to the code. The cornmittee in charge of preparing the recommendations for seismic provisions of NBCC is considering a suggestion by which the calculation of the design lateral forces will be carried out on the basis of new seismic hazard rnaps of Canada. The new hazard maps, prepared by the Geologicd Survey of Canada (GSC), are based on the response spectral ordinates, rather than on the peak ground velocity or peak ground acceleration. It is expected
that the future version of NBCC will require a building to be designed on the basis of these spectra, which are called, the uniform hazard spectra (UHS).
