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. National codes and guidelines are in place for the seismic design, evaluation, and upgrading of building structures in Canada.

As the voice of the U. The planned timelines for the development of these tools are as follows:. However, as a result of damage caused by recent earthquakes, focus has shifted to the behaviour of OFCs in overall building performance. 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.

Upgrade options for operational and functional components OFCs shall be considered. New buildings shall be designed and constructed in accordance with the seismic requirements of the current National Building Code of Canada.

The required Minimum level of seismic resistance for existing buildings to satisfy life safety requirements assuming National Building Code of Canada seismic loading requirements as the baseline is to be determined through a risk-based approach taking into consideration of the following three factors:.

Please first verify your email before subscribing to alerts. Seismic requirements for existing buildings undergoing significant projects are to be in compliance with this section. However, the application of this Standard can result in continued functionality and operation for certain OFCs, depending on the intensity of shaking and the level of over-design introduced in the mitigation scheme.

A higher level of upgrading, beyond the minimum established in this Seismic Standard, shall be considered. To obtain further information or to contact your regional representative, please contact tpsgc. You may delete a document from your Alert Profile at any time.

It is important that building owners, building designers, utility designers, and geotechnical experts coordinate the interface design and details. Examples include emergency response facilities, electric power systems, telecommunication systems, water supply, wastewater collection and treatment systems, hospitals and nursing homes, large assembly occupancies, industrial risk-generating facilities, laboratories and hazardous materials, art galleries and museums, and correctional institutions see Annex G.

Buildings in Canada that are designed in accordance with early codes can be vulnerable to the failure or malfunctioning of OFCs cea an earthquake. Systems comprising several OFCs especially those involving fluid or gas flow require careful assessment of interconnections. Subscription pricing is determined by: For example, a seismic resistance of 0. The main cause of casualties and property damage in the event of an earthquake is often the failure of these OFCs.

These systems require special interfacing design and details at the building junction to allow for differential movements between the building and its surrounding environment.

Planned additions to existing buildings are considered to be under the category of new buildings. Standards Subsctiption may be the perfect solution.

Annexes are designated normative mandatory or informative non-mandatory to define their application. Definitions for quality of inspection and degree of redundancy are based on industry practice and Standard. The classification of consequences of failure is based on recent research conducted by the Cs Research Council refer to Relevant Technical Documentation below. Earthquakes have rendered many buildings s82 due to extensive damage to their operational and functional components OFCs commonly referred to as non-structural componentsincluding building contents.

Guidelines for the seismic risk reduction of OFCsalso known as non-structural building components that is, building contents, bookcases, piping, light fixtures, etc. In a number of cases, improvements to the overall seismic performance of the building can be achieved by improving the performance of OFCs.

This Standard does not address those OFCs which are lightweight, non-hazardous, and relatively inexpensive in the context of the building and its functionality.

Due consideration shall be given to internally fragile OFCs equipped with stop anchors or snubbers comprising air gaps as large shock accelerations may be induced if the OFC impacts on its supports during strong shaking [see Clause 9. You can download and open this file to your own computer but DRM prevents opening s8322 file on another computer, including a networked server.

Please first log in with a verified email before subscribing to alerts. The new guideline will also provide information on the general understanding of both the potential seismic deficiencies and the methods of seismic upgrading of stone masonry structures.

Most complex OFCs containing electronic parts, for example that are used in high seismic areas are designed and built with internal seismic isolation and subjected to seismic qualification testing.

Seismic Standard

Changes to this edition include a harmonization with the National Building Code of Canada NBCC; b a general reorganization of contents; c revisions in definitions and symbols; d update of references; e revised definitions of OFC performance objectives; s8322 a revised clause Clause 5 on procedures w832 OFCs in new buildings; g new flowcharts Figures 3 to 5 to better illustrate the various procedures described in this Standard; h a revised clause Clause 7. This Standard is intended to address the need to reduce the seismic risk of OFCs and vsa improve the post-earthquake functionality of buildings.

Such work must be undertaken by a qualified professional engineer. 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 a832 considered structural components.

The objective is to provide a consistent risk management approach. Where a seismic upgrade is deemed necessary, the upgraded structure must have a seismic resistance that at least meets the minimum level as outlined in the Seismic Standard.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. External seismic hazards such as potential failure of service lifelines, ground failures outside the building, and business resumption after an earthquake are not addressed in the Seismic Standard. A building is made up of components that can be divided into two groups: 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.

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.

PSPC has been working with the NRC cwa update the following seismic screening and seismic evaluation tools for cas use on existing buildings. PSPC is developing a new guideline to aid the seismic assessment of stone masonry structures. Need more than one copy? If the document is revised or amended, you will be s82 by email.
