What is double R.C. beam?
The beam should be analyzed to find out the cause of deflection, then decide on the repair technique. one solution could be increasing the size of the beam and adding extra reinforcement in order load carrying capacity of the beam, and increase flexural resistance to reduce deflection.

The beam should be analyzed to find out the cause of deflection, then decide on the repair technique. one solution could be increasing the size of the beam and adding extra reinforcement in order load carrying capacity of the beam, and increase flexural resistance to reduce deflection. Before application of this repair technique, the beam should be released from certain amount of loads through the provision of jacks for the secondary beams. The new cross section with the added reinforcement ratio should be analyzed for compute its load carrying capacity.

The beam, which is reinforced from both zones i.e., compression and tension, that beam is said as Doubly Reinforced beam. It is usually given when the depth of the beam is constricted.

The beam, which is reinforced from both zones i.e., compression and tension, that beam is said as Doubly Reinforced beam. It is usually given when the depth of the beam is constricted. It is obviously not safe to provide a singly r/f beam with min depth resulting in failure due to insufficient resistance to oppose the bending moment.
Moment of resistance could not be increased by increasing the steel in the tension zone. Rather it can be increased by increasing the reinforcement, but it should not exceed 25% of the strained side. That’s why a doubly reinforced beam is provided to increase the moment of resistance of a beam having limited dimensions.
