Scope

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 does not apply to public utility structures or to bridges used solely for railway or rail transit purposes.

This Code 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 the Aapproval by the Owner.

Scope

This Section specifies requirements for the design of conventional movable highway bridges, i.e., bascule (including rolling lift), swing, and vertical lift bridges and deals primarily with the components involved in the operation of such bridges. The requirements for fixed span bridges, as given in other sections of the Code, shall apply to movable bridges, except as otherwise provided.

Scope

This Section specifies minimum requirements for the rehabilitation of bridges but is not applicable to the resolution of construction deficiencies of new structures. The requirements specified in this Section relate only to condition assessment, loads, load factors, resistances, and other design criteria relevant to the rehabilitation of bridges including required remaining service life, and assessment of ongoing deterioration and its impact on structural integrity.  Material specifications,  and rehabilitation procedures and maintenance procedures are not covered in this Section. but should conform to accepted Canadian good practice.

Scope

This Section specifies loads, load factors, and load combinations to be used in calculating load effects for design. Resistance factors required to check ultimate limit states criteria in accordance with Clause 3.4.2 are specified elsewhere in this Code. Loadings provisions for evaluation of existing structures are covered in Section 14 and for rehabilitation in Section 15.

This Section includes requirements related to the vibration of highway and pedestrian bridges. It also includes requirements related to construction loads and temporary structures; these apply to partially completed structures and structures necessary for construction purposes. Snow loads are not specified because in normal circumstances the occurrence of a considerable snow load will cause a compensating reduction in traffic load.

fully or partially prestressed concrete beams and slabs;

non-prestressed concrete beams, slabs, and deck slabs;

externally and internally restrained deck slabs;

stressed wood decks;

barrier walls;

existing concrete elements with externally bonded fibre-reinforced polymer (FRP) systems and near-surface-mounted reinforcement (NSMR); and

existing timber elements with externally or internally bonded glass-fibre-reinforced polymer systems (GFRP) and NSMR.

1.1.2 Fibres

This Section covers fibre reinforcement in which the fibre comprises one or more of the following:

glass;

carbon;

aramid;

a low modulus polymer or polymers; and

steel.

1.1.3 Matricies

This Section covers fibre-reinforced composites in which the matrix comprises one or more of the following:

6.1  Scope 

 

This Section specifies minimum requirements for the design of foundations and geotechnical systems (including highway embankments) under static loading conditions and for requirements pertaining to geotechnical investigations and design reports. This Section includes requirements for investigation to support seismic design, specifies minimum requirements to evaluate seismic resistance of foundations, and provides seismic performance requirements for geotechnical systems. This Section also includes requirements for investigation to support design of buried structures, although design of buried structures fall within the scope of Section 7.

Where conflict occurs between requirements in references to other standards or Codes and Section 6, the requirements of Section 6 shall take precedence.
