Abstract:

Glass fiber-reinforced polymer (GFRP) reinforcement is currently only allowed to be used in concrete structures in Seismic Design Category (SDC) A. An approach explored in this article is the use of GFRP reinforcement for structural elements that are not intended to be part of the inelastic (yielding) mechanism of the seismic force-resisting systems.

Abstract:

This month’s Q&A discusses the reinforcement stiffness ratio ρne that can be used for comparing the performance of various reinforcement types in slabs-on-ground and the design approach for glass fiber-reinforced polymer reinforcement in ACI/NEx MNL-6(23) based on percent reduction in unrestrained shrinkage strain from the enhanced aggregate interlock design of ACI PRC-360-10.

Abstract:

A new certification program co-sponsored by NEx: An ACI Center of Excellence for Nonmetallic Building Materials is now available through ACI Certification. The program, titled “GFRP Reinforcing Bar Inspector” is designed to qualify individuals responsible for inspecting the installation of glass fiber-reinforced polymer (GFRP) reinforcing bars in concrete construction. This program reinforces NEx’s mission to advance the safe and effective use of nonmetallic materials.
