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.
