Explain the doubly reinforced structure.
A doubly reinforced structure is created when steel reinforcement is added to a reinforced concrete design on both the tension and compression sides of a structural element, such as a beam. This is necessary when the load exceeds the capacity of a singly reinforced beam, which is one that only has steel on the tension side.
Double-reinforced structures have a higher load-bearing capacity because they can withstand greater moments and shear forces. They are used when space prevents a beam from being deeper than necessary or when heavier loads call for more strength. This type of structure not only improves durability, deflection resistance, and crack control, but it is also ideal for cantilever or overhanging beams and for strengthening pre-existing structures.
