Why Concrete Beams Need Tension Steel
Easyreinforced concreteflexure
Main tension reinforcement in a reinforced-concrete beam is needed primarily because concrete is weak in:

- BTension
- CDensity
- DTemperature

Answer: B. Tension
Concrete has relatively low tensile strength. Reinforcing steel carries the tensile force after the concrete cracks in the tension region, while concrete primarily resists compression.
