Reinforced concrete beams are structural members that support the transverse load which usually rest on supports at its end. Girder is a type of beam that supports one or more smaller beam.
Types of Concrete BeamsBeams are classified as
- Simple Beam
- Continuous Beam
- Semi-Continuous Beam
- cantilever beam
- T- beam
1. Simple Concrete BeamsSimple concrete beam refers to the beam having a single span supported at its end without a restraint at the support. Simple beam is sometimes called as simply supported beam. Restraint means a rigid connection or anchorage at the support.

2. Continuous BeamIt is a beam that rest on more than two supports. It can be a single beam provided for long span between columns or walls with intermediate supports of smallar beams or a single continuous beam for entire length of the structure with intermediate column or wall supports.

3. Semi-Continuous BeamRefers to a beam with two spans with or without restraint at the two extreme ends.

4. Cantilever BeamCantilever beams are supported on one end and the other end projecting beyond the support or wall.

5. T - BeamWhen floor slabs and beams. are poured simultaneously producing a monolithic structure where the portion of the slab at both sides of the beam serves as flanges of the T-Beam. The beam below the slab serves as the web member and is sometime called stem.
