A material-performance-based database for FRC and RC elements under shear loading
The shear strength of elements reinforced by fibres is predicted by Codes using formulations generally developed from a limited set of test results. In fact, only few of available test results are combined wit...

Recommendations for Future Research
A new push-off test should be performed subject to direct shear loads, with good control of crack width, in order to improve the response of the test in determining aggregate interlock in different concrete ma...

Experimental Tests to Study the Influence on the Shear Behavior of Fibers of Different Characteristics
Steel fiber reinforced concrete (SFRC) is a composite material that is characterized by an enhanced post-cracking behavior due to the capacity of fibers to bridge the crack faces.

Experimental Tests on Fibers Influence on the Size Effect on Shear
In this chapter it will be discussed the possibility of steel fibers to mitigate the size effect in large beams. For that, an experimental program consisting in 9 beams with h = 500, 1,000 and 1,500 mm, made w...

Literature Survey on Shear in FRC Beams
This chapter appears as inspiration for the affirmation of Fenwick and Paulay in 1968: “An inquiring designer will not only want to know how to apply a safe design procedure, but also wish to see the reason wh...

Experimental Tests on Hollow Core Slabs Made with FRC
Hollow Core Slabs (HCS) are usually precast by extrusion and it is not easy to place stirrups; thus, it is difficult to guarantee shear resistance in some cases.

Are steel fibres able to mitigate or eliminate size effect in shear?
This paper reports some recent results of an experimental campaign on fibre reinforced concrete (FRC) beams under shear loading tested at the University of Brescia: nine full scale beams, having a height varyi...

Shear Behavior of Self-Compacting Concrete and Fiber-Reinforced Concrete Push-Off Specimens
The shear behavior of reinforced “Z”-shaped push-off specimens made with self-compacting concrete (SCC) and self-compacting fiber-reinforced concrete (SCFRC) was analyzed by means of experimental tests. Testin...
