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.

However, as a result of damage caused by recent earthquakes, focus has shifted to the behaviour of OFCs in overall building performance. In a number of cases, improvements to the overall seismic performance of the building can be achieved by improving the performance of Cwa. Standards Subsctiption may be the perfect solution. As the voice of the U.

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. 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 cssa and techniques.

Seismic Standard

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. Buildings in Canada that are designed in accordance with early codes can be vulnerable to x832 failure or malfunctioning of OFCs after an earthquake.

Some examples of building components and sub-components are listed in Figures 1 and 2. The objective is to provide a consistent risk management approach.

It supersedes the previous editions published in and 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.

Already Subscribed to this document. External seismic hazards such as potential failure of service lifelines, ground failures outside the building, and business resumption after an earthquake are s82 addressed in the Seismic Standard.

These systems require special interfacing design and details at the building junction to allow for differential movements between the building and its surrounding environment. Seismic resistance of the building shall be expressed as a percentage of the current National Building Code of Canada requirements for new buildings. In many cases, losses associated with damage to these components are considerably greater than damage to the structural system.

We have no document history for this standard. National codes and guidelines are in place for the seismic design, evaluation, and upgrading of building structures in Canada. 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. 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.

Systems comprising several OFCs especially those involving fluid or gas flow require careful assessment of interconnections. Most complex OFCs containing electronic parts, for example that are used in high seismic areas are designed and built sca internal seismic cxa and subjected to seismic qualification testing.

For example, a seismic resistance of 0. Your Alert Profile lists the documents that will be monitored. This standard is not included in any packages. 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. Seismic requirements for existing buildings undergoing significant projects are to be in compliance with this section.

New buildings shall be designed and constructed in accordance with the seismic requirements of the current National Building Code of Canada.

A building is made s8832 of components that can be divided into two groups: PSPC has been working with the NRC to update the following seismic screening and seismic evaluation tools for the use on existing buildings. 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:.

We have no amendments or corrections for this standard. Please first verify your email before subscribing to alerts. Definitions for quality of inspection and degree of redundancy are based on industry practice and Standard.

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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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.

This Standard is intended to address the need to reduce the seismic risk of OFCs sca thus improve the post-earthquake functionality of buildings.

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.

Need more than one copy? Due consideration shall be given to internally fragile OFCs equipped with stop anchors or snubbers comprising air gaps csw large shock accelerations may be induced if the OFC impacts on its supports during strong shaking [see Clause 9. Planned additions to existing buildings are considered to be under the category of new buildings. Please first log in with a verified email before subscribing to alerts. PSPC is developing a new guideline to aid the seismic assessment of stone masonry structures.

Risk to safety, damage to property, and loss caa 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.
