The ACI Recommended Practice Guidelines for FRP Bars in Pre-Engineered Projects provide practical information on how to work with and install non-metallic glass fiber-reinforced polymer (GFRP) reinforcement. It details the key considerations for where to use GFRP reinforcement, the types of GFRP reinforcement available, and how to plan for installing this type of reinforcement. The key attributes of GFRP reinforcement and its proper use are also discussed.
In addition, the ACI Recommended Practice Guidelines for FRP Bars in Pre-Engineered Projects provides prescriptive design tables for common applications such as residential foundation walls and slabs-on-ground. The tables presented are similar to the prescriptive tables in “Code Requirements for Residential Construction and Commentary” (ACI 332). They are meant to allow contractors to understand how to select the appropriate size, location, and spacing of GFRP reinforcement for a project and to compare the layout of GFRP reinforcement to steel reinforcement.
This educational document for using FRP reinforcement has been made possible in part by the sponsorship of NEx. NEx is a subsidiary of the American Concrete Institute that partners with leading organizations focused on accelerating the use and technology of nonmetallic materials and products in construction.
