Special Issue Information
Dear Colleagues,
Concrete is the second most used material in the world after water. Unfortunately, concrete can be brittle, which means that it requires frequent repairs (thereby increasing its cost), has a reduced service life, and if that brittleness is not dealt with properly, there may be catastrophic consequences. Fibre-reinforced concrete has been researched in the past to overcome this issue by, for example, minimising crack propagation and hence providing resistance for water ingress. However, the incorporation of fibres leads to a reduced workability, and it is thus difficult to achieve a workable mix. Nevertheless, fibre-reinforced concrete is popular as it provides increased ductility and energy absorption compared to plain concrete. More recently, this area of research has attracted increased interest due to its sustainability, especially considering the potential use of recycled fibres and/or different fibre types/sizes.
This Special Issue aims to focus on three broad areas of the use of fibres in concrete: material characterisation in terms of general mechanical properties as well as durability properties; structural performance leading to the design of structures with this material; and the application fibre-reinforced concrete in general.
It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

Abstract: Torsional behavior and analysis of Steel Fiber reinforced concrete (SFRC) beams is being investigated since 1980’s. However, no unified or widely accepted model exists in the literature yet. Safe and cost-effective design requires simple and accurate formulation of SFRC structural members under torsion. The purpose of this study is twofold; to examine the torsion strength models for SFRC beams available in the literature and to address properly verified design formulations for SFRC beams under torsion. A total of almost 200 SFRC beams tested under torsion from 17 different experimental investigations around the world are compiled. The few strength models available from the literature are adapted and used to calculate the torsional strength of the tested beams. The predicted torsional strength is compared with the experimental values measured by the performed tests. Comparisons showed a room for improvement. First, a proposed model is based on optimizing the available models from the literature using linear regression. Further, a second model is proposed, which is based on modifying the American Concrete Institute (ACI) design code for Reinforced Concrete (RC) members to include the effect of steel fibers on the torsional capacity of SFRC beams. Applications of the proposed models showed better compliance and consistency with the experimental results compared to the available design models providing safe and verified predictions. The second model implements the ACI code for RC using a simple and easy-to-apply formulation.
