Structural Performances of Concrete Beams with Hybrid (Fiber-Reinforced Polymer-Steel) Reinforcements

Journal of Composites for Construction, 2002
The paper analyzes the structural behavior of concrete beams reinforced with hybrid fiber-reinforced polymer (FRP)-steel reinforcements. The analysis refers to concrete beams reinforced with FRP rebars placed near the outer surface of the tensile zone, with low cover thickness values, and steel rebars placed at the inner level of the tensile zone, with

Dynamic mechanical properties of hybrid fiber reinforced concrete

International Journal of Protective Structures, 2022
In this study, the dynamic mechanical properties of hybrid fiber reinforced concrete (HFRC) are analyzed with respect to failure mode, dynamic increase factor (DIF), and peak strain by means of a SHPB testing apparatus. The factors that influence the dynamic mechanical properties include fiber type and fiber content.

Behaviour of Concrete Beams Reinforced with Hybrid Fiber Reinforced Bars

Advanced Composite Materials, 2011
Due to the linear elastic behaviour of FRP bars, the flexural behaviour of FRP reinforced beams exhibits no ductility as occurs in the steel reinforced structures.

Hybrid Fiber–Reinforced Concrete with Unsorted Recycled-Tire Steel Fibers

Journal of Materials in Civil Engineering, 2017
In modern waste-management systems, an advantage is given to waste recycling and reuse, rather than to disposal. In the perspective of various initiatives taken worldwide in an attempt to convert waste materials into new products, the objective of this paper is to quantify contribution of unsorted recycled steel fibers from waste tires (RTSF) for use ...

Toughness enhancement in steel fiber reinforced concrete through fiber hybridization

Cement and Concrete Research, 2007
Crimped steel fibers with large diameters are often used in concrete as reinforcement. Such large diameter fibers are inexpensive, disperse easily and do not unduly reduce the workability of concrete. However, due to their large diameters, such fibers also tend to be inefficient and the toughness of the resulting fiber reinforced concrete (FRC) tends ...

Research on Hybrid Fiber Reinforced Concrete Lining Segments

Key Engineering Materials, 2018
Numerous cases on tunnel fires emphasized the importance of fire protection of tunnel lining and indicated that fire may cause severe damages to tunnel lining in term of concrete spalling, reduction of physical-mechanical characteristics and load bearing capacity. Hybrid Fiber Reinforced Concrete (HFRC) as a new type of composite building materials has

HYBRID FIBER REINFORCED CONCRETE

2007
This paper describes the mechanical performance of hybrid fiber concrete with a maximum fiber dosage of 0.75 Vol.%. Two types of fibers were used: short straight steel fibers and long hooked-end steel fibers. The concrete compressive strength (fc,cub150) varied between 55 and 65 MPa, dependent on the fiber mixture.

Mechanical properties of layered hybrid fiber reinforced concrete

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2003
To improve the mechanical properties of concrete, Layered Hybrid Fiber Reinforced Concrete (LHFRC) was developed in this paper. Through comparative tests, the effects of layered hybrid fibers on a series of mechanical properties of concrete were discussed.

Mechanical properties of polypropylene hybrid fiber-reinforced concrete

Materials Science and Engineering: A, 2008
This paper investigates the mechanical properties of polypropylene hybrid fiber-reinforced concrete. There are two forms of polypropylene fibers including coarse monofilament, and staple fibers. The content of the former is at 3 kg/m3, 6 kg/m3, and 9 kg/m3, and the content of the latter is at 0.6 kg/m3.
