Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.It is ...
iii) Partially over reinforcement : When either the transverse or longitudinal reinforcement yields before the crushing of concrete. Ultimate torsional strength of the section can be determined by considering idealized failure plane based on skew bending failure. It is contributed by the strength of concrete and strength of web reinforcement.

preclude the FRP rupture failure. On the other hand, if more FRP is used, the concrete crushing may occur prior or just following the yielding of reinforcing steel. At this time, a maximum amount of FRP, Af,max, should be provided to avoid premature crushing of concrete. Af,max and Af,min can be determined by

The design philosophy for FRP-reinforced concrete is based on principles of equilibrium, compatibility of strains, and the stress-strain characteristics of the materials involved. The brittle behavior of both FRP reinforcement and concrete must be considered. Crushing of the concrete or FRP rupture are the mechanisms that control the

1)Crushing Failure. When reinforced concrete columns are axially loaded, the reinforcement steel and concrete experiences stresses. When the loads are high compared to cross-sectional area of the column, the steel and concrete reach the yield stress and column fails …
Standard bends in reinforcing bars are described in terms of the inside diameter of bend because this is easier to measure than the radius of bend. The primary factors which control the minimum bend diameter are feasibility of bending without breakage and avoidance of crushing the concrete inside the bend.

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.
Application of Reinforced type PDC cutter Reinforced type PDC cutter are widely used to manufacture PDC drill bits. The scrap and used PDC cutters can be used to cut stone. Terrex impact crusher blow bars for crushing reinforced concrete with rebar
Results of an experimental investigation of isolated reinforced concrete structural walls subjected to inelastic load reversals are discussed and evaluated. Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered in this paper.

A reinforced concrete beam is made up of concrete and reinforcing steel. Concrete can only carry compression, and when the compressive stress exceeds the yield strength of the concrete, it fails by crushing (brittle failure).
Where the quantity of stirrup is excessive, the concrete would crush before the yielding of the stirrup reinforcement, resulting in the web-crushing mode of failure [2,3].
In reinforced concrete beam design, failure is designed for safety. If the structure fails by sudden crushing, huge damage and loss of life may take place. So, it is designed so that structure would give a warning before collapse.
Steel yielding followed by concrete crushing: The ﬂexural strength of the beam is reached with yielding of the tensile steel reinforcement followed by crushing of the concrete in the com-pression zone, while the FRP is intact. This happens if both the original and the strengthened beams are underreinforced.
