Introduction to Reinforced Concrete - Concrete, Steel, and Why They Work Well Together

Concrete and steel reinforcement combine into reinforced concrete, one on the most popular building systems on the planet. What makes these materials such a dynamic duo?

In this video, we learn about the stress-strain properties of concrete and steel, and why they complement each other. We then see how longitudinal reinforcement helps carry moments and transverse reinforcement (stirrups) helps carry shear in reinforced concrete beams. Finally, we progress through the loading stages of a concrete beam, starting uncracked, then cracked, and finally the yield plateau to failure.
