Such work must be undertaken by a qualified professional engineer.

Most complex OFCs containing electronic parts, for example s382 are used in high seismic areas are designed and built with internal seismic isolation and subjected to seismic qualification testing. As the voice of the U. It supersedes the previous editions published in and New buildings shall be designed and constructed in accordance with the seismic requirements of 8s32 current National Building Code of Canada.

Seismic resistance of the building shall be expressed as a percentage of the current National Building Code of Canada requirements for new buildings. Intrinsic functionality issues refer to the functionality of those OFCs that would be adversely affected by the malfunction of one or more elements damaged by the design earthquake.

Annexes are designated normative mandatory or informative non-mandatory to define their application. The optimum level of upgrade shall be selected based on a holistic review of financial, functional, operational, security, and client requirements, including a review of the Investment Analysis Report.

Earthquakes have rendered many buildings unusable due to extensive damage to their operational and functional components OFCs commonly referred to as non-structural componentsincluding building contents. The main cause of casualties and property damage in the event of an earthquake is often the failure of these OFCs. PSPC is developing a new guideline to aid the seismic assessment of stone masonry structures. We have no amendments or corrections for this standard.


Standards Subsctiption may be the perfect solution. Systems comprising several OFCs especially csaa involving fluid or gas flow require careful assessment of interconnections. Buildings in Canada that are designed in accordance with early codes can be vulnerable to the failure or malfunctioning of OFCs after an earthquake. This Standard does not address those OFCs which are lightweight, non-hazardous, and relatively inexpensive in the context of the building and its functionality. Please first verify your email before subscribing to alerts.

A higher level of upgrading, beyond the minimum established in this Seismic Standard, shall be considered. The objective is to provide a consistent risk management approach. PSPC has been working with the NRC to update the following seismic screening and seismic evaluation tools for the use on existing buildings.

The Canadian Standards Association CSA Standard provides information and methodology to identify and evaluate hazards caused by earthquake forces acting on OFCs and to undertake appropriate mitigation strategies and techniques.

Seismic Standard

For example, a seismic resistance of 0. This shall take into account factors such as future building use, seismic hazard, control of seismic damage to the building, post-disaster building use, heritage designation, and the cost differential for upgrading to a higher level versus the minimum.

The classification of consequences of failure is based on recent research conducted by the National Research Council refer to Relevant Technical Documentation below.

Risk to safety, damage to property, and loss of function and operation in a building can be significantly affected by the failure or malfunction of OFCs even if the building structural system has performed well during an earthquake. Some OFCs can contribute to the structural integrity of a building, depending on their location, type of construction, and method of fastening, but these are not generally considered structural components.


Subscription pricing is determined by: It is important that building owners, building designers, utility designers, and geotechnical experts coordinate the interface design and details.

In a number of cases, improvements to the overall seismic performance of the building can be achieved by improving the performance of OFCs. However, as a result of damage caused by recent earthquakes, focus has shifted to the behaviour of OFCs in overall building performance. Already Subscribed to this document. OFCs are divided into three categories of sub-components: Structural aspects are covered by the building codes and other publications referenced in Clause 2.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. The damage resulting from these components can be considerably more than that arising from structural component failure, particularly in areas of low and moderate seismic intensity.

However, the application of this Standard can result in continued functionality and operation for certain OFCs, depending on the intensity of shaking cs the level of over-design introduced in the mitigation scheme. When determining what constitutes a significant project, the long range plans for the asset must be reviewed in order to determine the most appropriate time to complete any necessary seismic upgrades mid-life retrofit, major base building recapitalization.
