65288a64fe It also specifies geometric requirements, based in part on the Transportation Association of Canada's Geometric Design Guide for Canadian Roads (1999), and hydraulic design requirements, based in part on the Transportation Association of Canada's Guide to Bridge Hydraulics (2004). Modifications were made to some of the response modification factors. Requirements for the design and testing of shock transmission units are included. This Code is not intended to apply to public utility structures or to bridges used solely for railway or rail transit purposes. Section 5 ("Methods of analysis") specifies requirements for analyzing the basic superstructure of a bridge. This Code could not have been developed without the cooperation of all of these sponsors.
-- Section 16 - Fibre-reinforced structures 16.1 Scope 16.1.1 Components The requirements of this Section apply to the following components containing fibre reinforcement: (a) fully or partially prestressed concrete beams and slabs; (b) non-prestressed concrete beams, slabs, and deck slabs; (c) externally and internally restrained deck slabs; (d) stressed wood decks; (e) barrier walls; (f) existing concrete elements with externally bonded fibre-reinforced polymer (FRP) systems and near-surface-mounted reinforcement (NSMR); and (g) existing timber elements with externally or internally bonded glass-fibre-reinforced polymer systems (GFRP) and NSMR. In its methods for simplified analysis of bridge superstructures, the beam analogy method approach is used and presented in a more concise manner. In accordance with CSA procedural requirements, however, responsibility for the technical content of this Code was assigned to the Technical Committee (TC), as were decisions on how to deal with the priorities and objectives identified by the RAC. The durability requirements for all of the materials are based on common principles applicable to the deterioration mechanisms for each material, the environmental conditions to which the materials are subjected, and the protective measures and detailing requirements needed to limit deterioration to acceptable levels. 16.1.2 Fibres This Section covers fibre reinforcement in which the fibre comprises one or more of the following: (a) glass; (b) carbon; (c) aramid; (d) a low modulus polymer or polymers; and (e) steel. Broad guidelines related to economic, aesthetic, and environmental considerations are also provided. Design provisions for ductile diaphragms have been added as energy dissipating systems for slab-on-girder bridges in the transverse directions. Section 13 ("Movable bridges") specifies requirements for the design, construction, and operation of conventional movable bridges, i.e.
