Beam is a structural member that supports the transverse load which usually rest on supports at its end. Girder – is the term applied to a beam that supports one or more smaller beam.
Beams are classified as:
a} Simple Beam
b) Continuous Beam
c) Semi-Continuous Beam
Simple 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.

Continuous Beam: It is a beam that rest on more than two supports.

Semi-Continuous Beam: – Refers to a beam with two spans with or without restraint at the two extreme ends.

Cantilever Beam:-Is supported on one end and the other end projecting ‘beyond the support or wall.

T – Beam: -When 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.
