Description

A multi-criteria and multi-level seismic risk management framework has been developed by NRC to ensure an acceptable and consistent level of risk for existing buildings in Canada with a focus on minimizing threats to life safety.

The framework consists of three levels: (1) Level 1: preliminary seismic-risk screening tool (PST); (2) Level 2: semi-quantitative seismic-risk screening tool (SQST); and (3) Level 3: seismic evaluation and upgrading guidelines (SEG).

Level 1 (PST) was developed based on a number of key criteria (seismicity, benchmark code edition, consequences of failure, and remaining occupancy time) to assist in exempting existing buildings from further assessment without the need for a site visit.

Level 2 (SQST) consists of three key components:

  1. structural scoring system that quantitatively assesses the structural seismic risk based on the probability of collapse;
  2. non-structural components scoring system that qualitatively evaluates the seismic risk of non-structural components based on the seismic demand of critical non-structural components; and
  3. ranking procedure that prioritizes buildings with potentially unacceptable seismic risk for the Level 3 (SEG) based on structural and non-structural components priority indices.

The Level3 (SEG) aims to identify the building deficiencies that lead to unacceptable seismic risk for existing buildings and to mitigate the identified deficiencies.
