The American Composites Manufacturers Association (ACMA, Arlington, Va.) announced on Sept. 18 the availability of three new guides to fiber-reinforced polymers (FRP) for concrete reinforcement. The documents are published by the American Concrete Institute (ACI) and developed by the ACI 440 technical committee, in which ACMA is a participant.
“With the publication of materials and construction specifications in mandatory language, ACI 440 has provided engineers and contractors with reference documents that save them an inordinate amount of time and, more importantly, give them the tools for safe and quality implementation of FRP as internal reinforcement to concrete,” says Dr. Antonio Nanni, professor and chair of the University of Miami’s Department of Civil, Architectural & Environmental Engineering. “It is an important step forward for the entire construction industry and ultimately the public.” Dr. Nanni is the primary author of ACI 440.5 and 440.6, two of the three new ACI publications.
The new publications include:
1. ACI 440.2R-08: Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures. This document offers general information on the history and use of FRP strengthening systems; a description of the unique material properties of FRP and committee recommendations on the engineering, construction, and inspection of FRP systems used to strengthen concrete structures. The guideline is based on information obtained from research, analytical work, and field applications of FRP systems. For more information and to order, go to 440.2R-08: Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures. $83.50 (ACI members $51.00); Order Code 440208.EM.
2. ACI 440.5-08: Specification for Construction with Fiber-Reinforced Polymer (FRP) Reinforcing Bars. This is a reference specification document that architects and engineers can apply to any construction project using fiber-reinforced polymer reinforcing bars. They would supplement the provisions of this reference specification as needed by designating or specifying individual project requirements. Standard units are available in hard copy or PDF format and a metric version is available in PDF format (metric version order code 4405M08). Go to 440.5R-08: Specification for Construction with Fiber-Reinforced Polymer (FRP) Reinforcing Bars. $28.50 (ACI members $18.00); Order Code 440508.EM.
3. ACI 440.6-08: Specification for Carbon and Glass Fiber-Reinforced Polymer (FRP) Bar Materials for Concrete Reinforcement. This material specification covers provisions governing testing, evaluation, and acceptance of carbon and glass fiber-reinforced polymer (FRP) bars used as reinforcement for concrete. Standard units available in hard copy or PDF format and metric version available in PDF format (metric version order code 4406M08). To learn more or to order this document, go to 440.6-08: Specification for Carbon and Glass-Fiber-Reinforced Polymer (FRP) Bar Materials for Concrete Reinforcement. $30.50 (ACI members $19.00); Order Code 440608.EM.
