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.

Various reinforcement types can be evaluated to determine their relative performance in controlling the restrained shrinkage cracking behavior of concrete. Two sets of published test data on restrained shrinkage cracking of slabs-on-ground are analyzed, and a parameter suitable for comparing the performance of various reinforcement types is identified.

This article introduces the latest fiber-reinforced polymer panel system developed by the author—SPiRe®+. These panels can serve as formwork, corrosion resistant reinforcement, and waterproofing. With their flat and smooth exterior face and protruding T-profiles on the interior face, the panels act as reinforcing elements for strengthening beams, slabs, and walls.

While completing concrete repairs, is it necessary to remove sound concrete if a nearby reinforcing bar exhibits rust? Can terms like corrosion or rust be used interchangeably? This month’s Q&A provides answers to these questions as well as a discussion on various factors influencing the extent of a repair of corrosion-related damage in concrete structures.

The limited availability of research studies related to the behavior of Steel Fiber Reinforced Concrete (SFRC) members subjected to torsion has hindered the development of clear and reliable design guidelines. Recent efforts by various researchers have been devoted to the development of analytical models for predicting the torsional response of SFRC members, supported by experimental results which have highlighted the efficiency of steel fibers in improving the torsional resistance and stiffness. For beams subjected to moderate or low levels of torsion, steel fibers, even at moderate dosages, have demonstrated the potential to replace minimum conventional torsion reinforcement, thus providing significant advantages for practical applications. This paper presents a discussion of the recent developments in research related to testing SFRC members under pure torsion. A comprehensive database of experimental test data is collated to provide a state-of-the-art in this respect. Additionally, the manuscript delves into analytical prediction models for the torsional capacity by some European code-oriented models, recently introduced by the Eurocode 2 as well as by the Authors of this paper. The results of model predictions are compared with available experimental data to assess the effectiveness and reliability of the models.
