Abstract
The National Research Council Canada is currently developing seismic evaluation and upgrading guidelines (SEG) for existing buildings in Canada. The SEG consist of both linear and nonlinear analysis procedures to evaluate the seismic adequacy of existing buildings. Where nonlinear analysis procedures are selected, nonlinear modelling parameters (NMP) and acceptance criteria (AC) are to be used. Due to the lack of Canadian guidelines for nonlinear analyses, the state of the practice in Canada often refers to ASCE/SEI 41 for guidance. Given the differences in seismic design and construction practices in the United States and Canada, ASCE/SEI 41 should be used with caution. This technical note presents a critical review of NMP and AC in ASCE/SEI 41 and recommends key steps for the investigation of the applicability of NMP and AC in ASCE/SEI 41 to the Canadian context. An example is included to demonstrate the recommended steps and the importance of such investigation.
