DESIGN PROVISIONS FOR FIBRE REINFORCED STRUCTURES IN THE CANADIAN HIGHWAY BRIDGE DESIGN CODE

摘要

The Canadian Highway Bridge Design Code (CHBDC), planned to be published in late 1996, is the successor of three editions of the Ontario Highway Bridge Design Code. The CHBDC has a new section dealing with the design of fibre reinforced structures. The provisions of this section, developed by a technical subcommittee of ten engineers from Canada, Japan and Germany, relate to the design of (a) fully, or partially, prestressed concrete beams and slabs, (b) concrete slabs and deck slabs with fibre reinforced plastic, (c) fibre reinforced concrete deck slabs of slab-on-girder bridges; (d) stressed wood decks; and (e) barrier walls. This paper presents the design provisions for these components and provides the details of their developmental background.
