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.

Seismic Standard – Technical Guides – NPMS – Real Property – PSPC

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 csx, art galleries and museums, and correctional institutions see Annex G.

However, as a result of damage caused by recent earthquakes, focus has shifted to the behaviour of OFCs in vsa building performance.

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. External seismic hazards such as potential failure of ccsa lifelines, ground failures outside the building, and business resumption after an earthquake are not addressed in the Seismic Standard.

Structural aspects are covered by the building codes and other publications referenced in Clause 2. Definitions for quality of inspection and degree of redundancy are based on industry practice and Standard.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. A higher level of upgrading, beyond the minimum cssa in this Seismic Standard, shall be considered. The objective is to provide a consistent risk d832 approach.

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

Subscription pricing fsa determined by: 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 csq for upgrading to a higher level versus the minimum.

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

Your Alert Profile lists the documents that will be monitored. The main cause of casualties cza property damage in the event of an earthquake is often the failure of these OFCs.

Such work must be undertaken by a qualified professional engineer. Need s83 than one copy? Upgrade options for operational and functional components OFCs shall be considered. Proceed to Checkout Continue Shopping. 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.

Seismic requirements for cza buildings undergoing significant projects are to be in compliance with this section. This standard is not included in any packages. This standard is also available to be included in Standards Subscriptions. Lifeline components in the immediate csw of the building and essential to its performance objective such as transformers, back-up power generators, fuel tanks, elevators, etc.

In many cases, losses associated with damage to these components are considerably greater than damage to the structural system. It supersedes the previous editions published in and 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.

Seismic Standard

We have no document history for this standard. For example, a seismic resistance of 0. These include, 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 W832 that would be adversely affected by the malfunction of one or more elements damaged by the design earthquake. These systems require special interfacing design and details at the building junction to allow for differential movements between the building and its surrounding environment.

Definitions of the appropriate consequence class for the two most common building occupancies for PSPCthat is office buildings and public buildings buildings to where the public are admittedare given in the Seismic Standard.

Buildings in Canada that are designed in accordance with early codes can be vulnerable to the failure or malfunctioning of OFCs after 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.

Notes to tables and figures are considered part of the table or figure and may be written as requirements. New buildings shall be designed and constructed in accordance with the seismic requirements of the current National Building Code of Canada.

As the voice of the U. You may delete a document from your Alert Profile at any time. Standards Subsctiption may be the perfect solution. The classification of consequences of failure is based on recent research conducted by the National Research Council refer to Relevant Technical Documentation below.

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. 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.

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

Seismic resistance of the building shall be expressed as a percentage of the current National Building Code of Canada requirements for new buildings. The planned timelines for the development of these tools are as follows:. PSPC is developing a new guideline to aid the seismic assessment of stone masonry structures. A building is made up of components that can be divided into two groups: OFCs are divided into three categories of sub-components: To obtain further information or to contact your regional representative, please contact tpsgc.

Annexes are designated normative mandatory or informative non-mandatory to define their application. If the document is revised or amended, you will be notified by email.
