Reinforced concrete - Wikipedia

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. The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the ...

Three Stages in the Life of a Reinforced Concrete Beam

Three Stages in the Life of a Reinforced Concrete Beam Reinforced concrete, considered "low‐tech" by some, is actually complex. It consists of two materials, steel and concrete; the concrete can be cracked or uncracked; and the load‐deformation behavior of both the steel and the concrete are non‐linear at failure.


Reinforced Concrete Beam - an overview | ScienceDirect Topics

As FRP rebars show linear behavior up to failure and do not have yielding stage as steel bars, the flexural failure of FRP-reinforced concrete beams is caused either by the concrete crushing or by FRP rupture, and the concrete becomes the ductile component. In order to achieve concrete failure first, control deflection and cracking, and satisfy ...

Reinforced Concrete Material Properties (Nonlinear)

The reinforced concrete material model is treated as statistically homogeneous with different tensile and compressive behaviors. It follows a "smeared" crack model where cracking and crushing are simulated via degeneration of the elasticity at integration points instead of tracking individual macroscopic cracks.
