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.

Lifeline components in fsa immediate vicinity of the building and essential to its performance objective such as transformers, back-up power generators, fuel tanks, elevators, etc. 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. 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.

Structural aspects are covered by the building codes and other publications referenced in Clause 2. Notes to tables and figures are considered part of the table or figure and may be written as requirements.

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. 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.

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.

Subscription pricing is determined by: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Your Alert Profile lists the documents that will be monitored. Planned additions to existing buildings are considered to be under the category of new buildings.

Seismic Standard

Systems comprising several OFCs especially those involving fluid or gas flow require careful assessment of interconnections. 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.

Seismic requirements for existing buildings undergoing significant projects are to be in compliance with this section. The objective is to provide a consistent risk a832 approach. It supersedes the previous editions published in and 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.

In many cases, losses associated with damage to these components are considerably greater than damage to the structural system. However, as a result of damage caused by recent earthquakes, focus has shifted to the behaviour of OFCs in overall building performance.

This standard is also available to be included in Standards Subscriptions. OFCs are divided into three categories of sub-components: This shall take into account ss832 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. Seismic resistance of the building shall be expressed as a percentage of the current National Building Code of Canada requirements for new buildings.

You may delete a document from your Alert Profile at any time. The planned timelines for the development of these tools are as sca. 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.

Definitions for quality of inspection s823 degree of redundancy are based on industry practice and Standard. 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:.

Need more than one copy? The new guideline will also provide information on the general understanding of w832 the potential seismic deficiencies and the methods of seismic upgrading of stone masonry structures.

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; s823 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.

Standards Subsctiption may be the perfect solution. Due consideration shall be given to internally fragile Fsa 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.
