New ACI 440.11 code adopted for design of concrete reinforced with glass-fiber-reinforced polymer bars

摘要

The American Concrete Institute has published ACI 440.11-22, Building Code Requirements for Structural Concrete Reinforced with Glass Fiber-Reinforced Polymer (GFRP) Bars-Code and Commentary. This new code was developed by an American National Standards Institute-approved consensus process and addresses structural systems, members, and connections, including cast-in-place, precast, nonprestressed, and composite concrete construction. ACI 440.11-22 is the first comprehensive building code covering the use of nonmetallic, GFRP reinforcing bars in structural concrete applications. This article provides background on this new code and discusses potential uses for precast concrete components and structures.
