An experimental study and finite analysis of punching shear failure in steel fibre-reinforced concrete ground -suspended floor slabs
… model for steel fibre-reinforcement (SFRC), to study experimentally the punching shear behaviour of SFRC with no longitudinal reinforcement and to develop a finite element model that can accurately predict the behaviour of SFRC slabs subjected to punching shear. In this respect, a …

Machine Learning Prediction of Shear Capacity of Steel Fiber Reinforced Concrete
… provisions for steel fiber-reinforced concrete (SFRC) in building codes. This is mainly due to the complex shear transfer mechanism in SFRC. Existing empirical equations for SFRC shear strength have been developed with relatively limited data examples, making their accuracy restricted to specific …

Numerical Modelling of Steel Fibre Reinforced Concrete Subjected to Fatigue Loading
… stresses. Steel Fibre Reinforced Concrete (SFRC) improves post-cracking behaviour through enhanced tensile strength, toughness, and crack control, offering increased resistance to fatigue damage. Despite extensive experimental research on SFRC, the fatigue behaviour of pre-cracked SFRC …

An experimental investigation into the effectiveness of steel fibre-reinforced concrete relative to conventional mesh-reinforced concrete in thin shell construction
… suitability of steel-fibre reinforced concrete (SFRC) as a building material. The performance of the SFRC is gauged relative to conventional steel mesh-reinforced concrete. The report begins with the historical background of fibre-reinforcing, its development and diversity in modern times. The …

Structural Behaviour of Self Consolidating Steel Fiber Reinforced Concrete Beams
… The use of steel fiber reinforced concrete (SFRC) could be considered as a potential alternative to the use of traditional shear reinforcement. Concrete is very weak and brittle in tension, SFRC transforms this behaviour and improves the diagonal tension capacity of concrete and thus can …

Performance of Steel Fiber-Reinforced Concrete Beams Under Shock Tube Induced Blast Loading
… (18) beams are tested, including fourteen (14) SFRC beams, and a companion set of four (4) beams built without fibers. Seven (7) of the beams are tested under quasi-static (slowly applied) loading with the remaining eleven (11) beams tested under simulated blast loading using the University of …

Strength and Performance of Steel Fiber Reinforced Concrete Post-Tensioned Flat Plates
… to the slab's failure. The performance of the SFRC post-tensioned flat plate indicated that considerations should be made to remove requirements for negative moment reinforcement in post-tensioned flat plates when SFRC is used. Also, the requirements for positive moment reinforcement should be …

Flexural Behaviour of Steel Fibre Reinforced Concrete Tunnel Linings
The promotion of steel fibre reinforced concrete (SFRC) as a construction material for tunnel linings has prompted a number of researchers to focus on methods of evaluating their flexural strength and stiffness. This thesis presents the results of an experimental and numerical investigation of the …

Analysis of crack patterns in reinforced concrete frames under seismic excitation
… different types of concrete (RC, HSRC and SFRC) in order to determine the one that will contribute the most to increase the steadiness of buildings in seismic regions at the connection between beams and columns. The first part of this paper consists of introducing these different types of …

Experimental study of UHPC with high fire resistance and meso-scale modelling
… conductivity of steel fibre reinforced concrete (SFRC) (including UHPC), a meso-scale model for heat analysis was developed. Delaunay triangulation was employed to generate the unstructured mesh for SFRC materials. The model was validated using existing experimental data. Then, it was used to …

The behaviour of steel fibre reinforced concrete material and its effect on impact resistance of slabs
… concrete mix. Steel Fibre Reinforced Concrete (SFRC) is popular FRC material that is being studied to improve the structural behaviour of members under different load conditions. This study aims to investigate and examine the structural behaviour of steel fibre reinforced concrete material at …

Performance of Steel Fiber Reinforced and Conventionally Reinforced Post-Tensioned Flat Plates
… for design of banded-banded PT system and SFRC post-tensioned flat plate. Additional testing should be conducted before SFRC post-tensioned flat plates are incorporated in the ACI 318 code (ACI 318, 2019) with a maximum allowable tensile stress of 6√(f'c).
