What is the main function of steel reinforcement in concrete structures?
Correct Answer: Steel reinforcement helps in resisting tensile forces in concrete.
- Step 1: Understand that concrete is a strong material but weak when pulled or stretched (this is called tension).
- Step 2: Know that steel is strong in tension and can handle pulling forces well.
- Step 3: Realize that by adding steel bars (reinforcement) to concrete, we can make the structure stronger against pulling forces.
- Step 4: Conclude that the main function of steel reinforcement is to help concrete resist these tensile forces.
