scope:

General

This Standard applies to OFCs in buildings with significant seismic hazards as defined in Clause 4.1.8.1 of the NBCC.

This Standard provides information and methodologies to identify and evaluate seismic hazards associated with OFCs and to undertake appropriate mitigation strategies and techniques. While seismic risk reduction of OFCs is affected by the structural performance of a building, this Standard does not address structural integrity (see Clause 1.3).

This Standard is intended for use by building owners, building officials, facility managers, engineers, architects, and other stakeholders for improving the safety and serviceability of OFCs subjected to earthquakes.
