A beam is a long slender member, a 2d element in structure having relatively longer span than the depth. Beam is designed to carry the bending moment and the shear forces if any. Based on the supports of the beam, Following are some of the classification of the beam.

Classification based on supports

The following are the important types of beams :-
a) Cantilever beam
b) Simply Supported beam
c) Overhanging beam
d) Fixed beams
e) Continuous beams
f) Propped Cantilever beam

Cantilever Beam

A beam which is fixed at one end and free at the other end is known as cantilever beam, Or from statics point of view a beam with fixed support at one end resisting all the vertical, horizontal and bending moment produced as a result of loading of the beam and is free at the other end is cantilever beam. The beam is shown ;-

Simply Supported Beam

As the name suggests a beam which is supported or resting freely on supports at its both ends is known as simply supported beam or from mechanics point of view, a beam with both hinge support resisting horizontal and vertical forces and roller support fixing only one vertical force is known as a simply supported beam as shown ;-

Simply Supported Beam 

Overhanging beam

If the end portion of the beam is extended beyond the support such a beam is known as overhanging beam. Mostly in overhanging beam one support is Hinge support while other is roller support having one end as free like a cantilever. The shape of the beam is shown :-

Overhanging beam 

Fixed Beam

A beam whose both ends are fixed or built-in walls, is known as fixed beam. A fixed beam is also known as built-in or encastred beam.  A fixed beam usually have reinforcement that is going through the beam into the column as shown.

Fixed end beams 


Continuous Beams 

A beam which is provided more than two supports or is continuous over more than two supports is known as continuous beam. Usually in frame structure a continuous beam is used which have both positive and negatives moments you will be able to calculate later on.


Continuous Beams


Propped Cantilever Beam

A propped Cantilever beam is a little modification of the cantilever beam, if the free end of the cantilever beam is place on a roller support than the resultant beam will be propped cantilever beam as shown ;-
