    New Specification for Solid Round Glass Fiber Reinforced Polymer Bars for Concrete Reinforcement

    (What is a Work Item?)

    Developed by Subcommittee: D30.10 | Committee D30 | Contact Staff Manager



    WK43339

    1. Scope

    1.1 This specification covers glass fiber reinforced polymer (GFRP) bars, provided in cut lengths and bent shapes, and having an external surface enhancement for concrete reinforcement. Bars covered by this standard must meet geometric, material, and physical properties described herein and are noted at Type 1 GRFRP bars. The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the specification. 1.2 The following FRP materials are not covered by this specification: 1.2.1 Bars made of more than one load bearing fiber type (that is, hybrid FRP), and 1.2.2 Bars having no external surface enhancement (that is, plain or smooth bars, or dowels), 1.2.3 Bars with geometries other than solid, substantially round cross sections. 1.2.4 Pre-manufactured grids and gratings made with FRP materials.

    This standard will be used by the architects, engineers, contractors, and building and bridge owners that specify composite FRP bars in civil structures. It is of considerable importance in standardizing and subsequently advancing the market for these products.
