CSA Group Supplement #1 to CAN/CSA-S6-06, Canadian Highway Bridge Design Code S6S1-10

Preface Supplement #1 to CAN/CSA-S6-06, Canadian Highway Bridge Design Code. In addition to minor updates throughout, this 1st Supplement includes extensive updates to the Section 10 Steel Structures and Section 14 Evaluation. 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. This 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 CSA S6.1S1-10 which provides rationale statements and explanatory material for many of the CHBDC clauses.
