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 is the second in the series of Q&A articles attempting to clarify some common questions and misconceptions about glass fiber-reinforced polymer (GFRP) reinforcing bars. Discussed topics include traceability, hybrid reinforcement, sustainability, elevated temperature and fire, seismic provisions, limitations, and splices and headed bars.

Abstract:

The Rob and Melani Walton Center for Planetary Health at Arizona State University, Tempe, AZ, USA, rises from a triangular lot like a giant cracked-open geode. Clad in a shell of glass fiber-reinforced concrete (GFRC), the building’s paneled façade is based on biomimicry of a saguaro cactus’ orientation to the sun.

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.
