Anchorage in reinforced concrete

When you want to keep something stuck in one place, you need to anchor it. Imagine your ball has a string attached to it and you tie this string to a tree. Now your ball will not move from that spot because it is anchored to the tree. Similarly, when we make reinforced concrete structures like buildings, bridges and roads, we need to anchor various parts so that they do not move from their place.

The anchorage is a special way to attach steel reinforcing bars (rebars) to concrete which is used in reinforced concrete structures. In simpler terms, we use large steel bars (rebars) and concrete together to make strong building structures. The rebars are very important as they help the reinforced concrete structure to resist different types of forces such as bending, stretching, compression, and twisting. It helps keep the reinforced concrete structure together and makes it stronger so that it does not break easily.

When we connect the rebars to concrete, we need to make sure they stay in place and cannot move. In order to do that, we use a special anchoring method. This anchoring method involves putting the rebars inside a special casing or housing which is called a "sleeve." This sleeve has special teeth or flaps that grip the rebars strongly. After the sleeve is attached to the steel rebars, it is filled with concrete. This way, the rebars are securely anchored and do not move from their place inside the concrete.

In summary, anchorage in reinforced concrete is the method of securely attaching steel rebars to concrete to make a strong structure that can resist different types of forces. We do this by using a special casing or housing called a sleeve that has teeth or flaps that grip the rebars tightly. By using this technique, we can create strong and durable reinforced concrete structures that are resistant to damage and can last for a long time.
