On the Effectiveness of Steel Fibers as Shear Reinforcement

ACI Structural Journal, 2013
An experimental study on steel fiber-reinforced concrete (SFRC) beams subjected to shear loading tested at the University of Brescia in recent years is presented and discussed. A total of 18 full-scale experiments were carried out, aimed at investigating the effect of randomly distributed steel fibers within the concrete matrix on shear behavior.

Effect of Corroded Steel Fibers on Mechanical Behavior of Steel Fiber Reinforced Concrete

2020
This paper presents the exposure test results of Steel Fiber Reinforced Concrete (SFRC) beams having crack width of 0.2 mm for 3 months, 1 year and 2 years. By flexural loading test, initial stiffness of the exposed SFRC beams was decreased with increasing of exposure period. And corrosion of steel fibers themselves was observed at crack surface.

Dynamic performance enhancement of RC slabs by steel fibers vs. externally bonded GFRP sheets under impact loading

Engineering structures, 2020
Recently, to improve the dynamic behavior of Reinforced Concrete (RC) slabs under impact load, the methods of externally bonding Glass Fiber Reinforced Polymer (GFRP) sheets to slab and internally reinforcing concrete by steel fibers have been proposed ...

How do steel fibers improve the shear capacity of reinforced concrete beams without stirrups?

Composites Part B: Engineering, 2019
Even though the structural behavior steel fiber reinforced concrete (SFRC) has been extensively researched, structural applications are still limited. One barrier to its implementation is the lack of mechanical models that describe the behaviour of SFRC ...

Effect of different fibers (steel fibers, glass fibers, and carbon fibers) on mechanical properties of reactive powder concrete

Structural Concrete, 2020
In the present study, reactive powder concrete (RPC) was investigated with three different types of single fibers that is, steel fiber (SF), glass fiber (GF), and carbon fiber (CF).

Influence of steel fibers on the flexural performance of concrete incorporating recycled concrete aggregates and dune sand

, 2020
The flexural performance of steel fiber-reinforced concrete made with recycled concrete aggregates (RCA) and desert dune sand was investigated. Natural aggregates were replaced by 30, 70, and 100% RCA.

Effect of steel fibers with galvanized coatings on corrosion of steel bars embedded in UHPC

Composites Part B: Engineering, 2019
Ultra-high-performance concrete (UHPC) is widely accepted for its super-high durability. However, the corrosion performance of steel reinforcing bars embedded in UHPC and the improved protection of UHPC cover to steel bars are seldom studied. Furthermore,

Improvement of flexural and tensile strength of layered-casting UHPC with aligned steel fibers

, 2020
In order to further improve flexural and tensile strength as well as ductility of ultra-high performance concrete (UHPC), this research developed an improved device for casting layered UHPC with better alignment of the fiber. The effect of fiber content (

Achieving slip-hardening behavior of sanded straight steel fibers in ultra-high-performance concrete

, 2020
This study develops a slip-hardening straight steel fiber in ultra-high-performance concrete (UHPC). For this, a surface treatment using sandpaper with various grits was adopted in both parallel and perpendicular directions to the fiber axis.
