Effect of Steel Fibre Content on the Fatigue Behaviour of Steel Fibre Reinforced Concrete
2012Rigid pavements are widely used for very heavily trafficked freeways because of their long design period and high performance. Rigid pavements are designed for two modes of failure, namely, fatigue and erosion. Most of the fatigue damage occurs due to very heavy axle loads. In this research, steel fibre was added to Portland cement concrete at 20 kg/m3

Fibre spacing in steel fibre reinforced composites
Matériaux et Constructions, 1977A method is presented which makes it possible to evaluate the fibre content or to estimate the distribution of fibres in steel fibre reinforced composite materials from the analysis of X-ray pictures. The basic notion in this method is an apparent fibre spacing defined as the average spacing between the intersections of individual fibre projections ...

Shear transfer across cracks in steel fibre reinforced concrete
Engineering structures, 2019Existing models for the shear strength of steel fibre reinforced concrete (SFRC) in general, and for the transfer of shear stresses across cracks, typically assume that the shear strength of plain concrete is increased by a so-called “fibre contribution”.

Volume Changes of Fibre Concrete with Steel and Synthetic Fibres
2006Abstract The verification and precise formulation of volume changes of structural concretes (creep, shrinkage) are very difficult (see models like: B3 - Bazant [8] or EC2 - European Standard [5], etc.). However, many structural analyses cannot be performed without considering the effects of those properties.

Segregation of Steel Fibres of UHPFRC
Solid State Phenomena, 2018The mixture of ultra-high performance concrete is often supplemented by steel fibres which can significantly improve the fracture energy of the concrete. The incorporation of steel fibres results in especially a significant increase of tensile strength and minimize the risk of brittle failure.

Steel fibre reinforced concrete (SFRC) has been increasingly used in the engineering structures subjected to intense dynamic loads. In structural design and analysis, a dynamic increase factor (DIF) has been usually used to characterize strain-rate ...

Light weight steel fibre reinforced concrete: A review
, 2020Steel fibre reinforced concrete (SFRC) could be a stuff that can decrease brittleness of concrete and can increase the malleability. SFRC is employed extensively to line the tunnels and alternative underground structures, to extend the thickness of ...

A new formulation is herein proposed to embed discrete fibres and cracks in finite elements. The main features of the fibre behaviour are automatically accounted for, including bond and snubbing effects.
