Seismic Design Requirements in the 2024 Ontario Building Code
The OAA has created a document on the Importance Category and Seismic Restraint updates in the Code.
The Ontario Association of Architects (OAA) is the regulatory body responsible for registering and licensing all architects legally entitled to practice the scope of architecture in the Province of Ontario. The OAA has created a helpful resource to help you understand seismic design requirements in the 2024 Ontario Building Code.
Seismic design is a critical factor for buildings designated to be available after an earthquake for emergency responders, treating victims, communications, and housing the displaced. Some areas of Ontario; the Ottawa and St. Lawrence valleys for example, are among the highest seismically sensitive areas in North America.
Although the requirement for the Importance Category resides in “Part 4 – Structural Design” of the Building Code, the
determination of Importance Category relates to the use and occupancy of the building.
