The New GFRP Bar Code

ACI recently published 440.11-22 Building Code Requirements for Structural Concrete Reinforced with Glass Fiber-Reinforced Polymer (GFRP)Bars. This code is most appropriate for concrete structures that would be vulnerable to corrosion of the steel reinforcement. Likewise, structures that require non-ferrous reinforcement due to electro-magnetic considerations are also good candidates for GFRP reinforcement. Lack of a design standard has limited the use of GFRP in these types of structures.

The purpose of this presentation is to introduce the new GFRP Bar Code. The presentation will discuss an introduction to GFRP rebar materials, an overview of what is covered in the Code, the full suite of standards needed by the designer and contractor, the major difference between reinforcing concrete with GFRP and steel, and some field applications of GFRP reinforced concrete structures.
