TYPES OF BEAMS & TYPES OF LOADINGS

Beam:-A structural member which is acted upon by a system of external loads at right angles to its axis is known as beam.

 

 

LOADING:-It is a type of weight put on the beam which causes the beam to deflect or bend in shape.

 

TYPES OF BEAMS:-There are five types of beams as under:-

 

1.Cantilever Beam:-A cantilever beam is one whose one end is fixed and the other end carries a point or concentrated load or no point load or concentrated load

2. Simply Supported Beam:-A simply supported beam is one which carries two reaction forces at its two ends or a point load at its mid-point

3.Overhanging Beam:-It is a type of simply supported beam which overhangs from its supports.An overhanging beam may overhang on one side only or on both sides of the supports.

4. Rigidly Fixed Or Built-In-Beam:-It is a type of beam in which both ends are fixed and carries a point load at its centre.

5. Continuous Beam:-It is a type of overhanging beam which consists of a numerous reaction forces and point loads.

TYPES OF LOADINGS:

 

A beam may be subjected to either or in combination of the following types of loads:-
 
 
1.Concentrated Or Point Load:-It is a type of load which acts at the centre of the beam as shown below:-

 

 

2. Uniformly Distributed Load:-It is a type of load which is distributed uniformly over the entire length of the beam.

 

 

 3. Uniformly Varying Load:-These are the loads varying uniformly from zero to a particular value and spread over a certain length of the beam.Such load is also called triangular load.
