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:. The main focus of the new guideline will be on strategies that can be used as a decision cwa tool for identification of the appropriate approach for the seismic assessment and upgrading of heritage masonry structures.

Some examples of building components and sub-components are listed csw Figures 1 and 2. Annexes are designated normative mandatory or informative non-mandatory to define their application. Guidelines for the seismic risk reduction of OFCsalso known as non-structural building components that is, building contents, bookcases, piping, light fixtures, etc. To obtain further information or to contact your regional representative, please contact tpsgc.

Standards Subsctiption may be the perfect solution. PSPC is developing a new guideline to aid the seismic assessment of stone masonry structures. These systems require special interfacing design and details at the building junction to allow for differential movements between the building and its surrounding environment.

We have no document history for this standard. In many cases, losses associated with damage to these components are considerably greater than damage to the structural system. PSPC has been working with the NRC to update the following seismic screening and seismic evaluation tools for the use on existing buildings.

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. The objective is to provide a consistent risk management approach. These ca, but are not limited to, building components such as canopies over exit ways, partitions, roof parapets, mechanical and electrical systems, ceilings, and cladding.

Intrinsic functionality issues refer to the functionality of those OFCs that would a832 adversely affected by the malfunction of one or more elements damaged by the design earthquake.

A higher level of upgrading, beyond the minimum established in this Seismic Z832, shall be considered. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Upgrade options for operational and functional components OFCs shall be considered. Your Alert Profile lists the documents that will be monitored. This standard is also available to be included in Standards Subscriptions.

Due consideration shall be given to internally fragile S82 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.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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 main cause of casualties and property damage in the event of an earthquake is often the failure of these OFCs. This standard is not included in any packages. For example, a seismic resistance of 0.

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. 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.

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. Such work must be undertaken by a qualified professional engineer. As the voice of the U. We have no amendments or corrections for this standard. 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.

In a number of cases, improvements to the overall seismic performance of the building can be achieved by improving the performance of OFCs. 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.

Lifeline components in the immediate vicinity of the building and essential to its performance objective such as transformers, back-up power generators, fuel tanks, elevators, etc. New buildings shall be designed and constructed in accordance with the seismic requirements of the current National Building Code of Canada.

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.

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.

OFCs are divided into three categories of sub-components: 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.

The new guideline will also provide information on the general understanding of both the potential seismic cwa and the methods of seismic upgrading of stone masonry structures.

Already Subscribed to this document. 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; f a revised clause Clause 5 on procedures for 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 does not address those OFCs which are lightweight, non-hazardous, and relatively inexpensive in the context of the building and its functionality. Buildings in Canada that are designed in accordance with early codes can be vulnerable to the failure or malfunctioning of OFCs after an earthquake.

A building is made up of components that can be divided into two groups: National codes and guidelines are in place for the cxa design, evaluation, and upgrading of building structures in Canada. Subscription pricing is determined by:
