CAN/CSA S6-2006 + S6S1-10

CAN/CSA-S6-06 + S6S1-10 - Consists of CAN/CSA-S6-06, Canadian Highway Bridge Design Code and S6S1-10, Supplement #1 to CAN/CSA-S6-06, Canadian Highway Bridge Design Code

Intended Use

In Canada, the legal mandate for establishing design and construction requirements for highways,
including highway bridges, lies with the provincial and territorial governments. The Canadian Highway Bridge Design Code (CHBDC) was developed to provide a state-of-the-art model design code that could be adopted by all provinces and territories.

The CHBDC establishes safety and reliability levels for highway bridges that are consistent across all Canadian
jurisdictions. It makes it easier for the consulting and producer industries to respond to calls for proposals and also supports the implementation of a national highway transportation system with agreed minimum standards and loadings for bridges on interprovincial highways, thereby encouraging consistency of vehicle weights across jurisdictions and supporting the objective of more cost-effective transportation of goods.

The CHBDC uses the limit states design approach and reflects current design conditions across Canada as
well as research activity since the publication of the previous edition. The 1st Supplement to the CHBDC includes significant updates to Section 3 "Loads and Load Factors", Section 5 "Methods of Analysis", Section 10 "Steel Structures", Section 14 "Evaluation" and Section 16 "Fibre Reinforced Structures".

This Supplement is complemented by S6.1-06 + S6.1S1-10 which provides rationale statements and explanatory material for many of the CHBDC clauses.

Preface

This is the tenth edition of CAN/CSA-S6, Canadian Highway Bridge Design Code. It supersedes the previous edition published in 2000, which amalgamated and superseded CAN/CSA-S6-88, Design of Highway Bridges, and the Ontario Ministry of Transportation's OHBDC-91-01, Ontario Highway Bridge Design Code, 3rd ed. Earlier editions of the CSA Standard were published in 1978, 1974, 1966, 1952, 1938, 1929, and 1922. Earlier editions of the Ontario Highway Bridge Design Code were published in 1983 and 1979 by the Ontario Ministry of Transportation.

1.1 Scope

1.1.1 Scope of Code

This Code applies to the design, evaluation, and structural rehabilitation design of fixed and movable highway bridges in Canada. There is no limit on span length, but this Code does not necessarily cover all aspects of design for every type of long-span bridge. This Code also covers the design of pedestrian bridges, retaining walls, barriers, and highway accessory supports of a structural nature, e.g., lighting poles and sign support structures.

This Code is not intended to apply to public utility structures or to bridges used solely for railway or rail transit purposes.

This Code also does not specify requirements related to coastal effects (e.g., exposure to sea action and icebergs) or to mountainous terrain effects (e.g., avalanches). For structures that can be subject to such effects, specialists need to be retained to review and advise on the design and to ensure that the applicable requirements of other codes are met.

For bridges not entirely within the scope of this Code, the requirements of this Code apply only when appropriate. Necessary additional or alternative design criteria are subject to Approval.
