Reinforced Concrete beams - Structural Engineer Calcs

Moreover, concrete is strong in compression and very weak in tension. Thus, Steel reinforcement used to take up tensile stresses in reinforced concrete beams. A reinforced concrete beam is used as much below the ground level as above it. However, reinforced concrete is a very strong and versatile material. It also has an excellent fire resistance.

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete ...
