| Abstract | The Level 1 – Preliminary Seismic Risk Screening Tool (PST) for existing wood light frame buildings under Part 9 of the NBC (WLF-P9) aims to quickly identify and exempt existing WLF-P9 buildings with acceptable seismic risks from further seismic risk assessment. The methodology in Level 1 – PST (WLF-P9) is based on Level 1 – PST originally developed for existing Part 4 buildings. Level 1 – PST (WLF-P9) is designed to be completed by trained screeners using Level 1 – PST (WLF-P9) screening forms. A site visit is not required as the building information for completing the form can be collected in office. Major changes made to the original Level 1 – PST for existing Part 4 buildings are summarized as follows:
1. The benchmark NBC edition for existing WLF-P9 buildings have been identified by tracking the evolution of design provisions in Part 9 of the NBC.
2. Consequences of failure have been determined for existing WLF-P9 buildings.
3. The seismic risk acceptance criteria have been updated to suit the characteristics and seismic behaviour of existing WLF-P9 buildings.
4. The Level 1 – PST screening form has been modified to reflect the changes. |
