# Different Types of Beams :

Beams are classified into many types based on three main criteria.

1. ### Based on Geometry

1. Straight beam – Beam with straight profile
2. Curved beam – Beam with curved profile
3. Tapered beam – Beam with tapered cross section
4. Based on the shape of cross section
1. I – Beam – Beam with “I” cross section
2. T – Beam – Beam with “T” cross section
3. C – Beam – Beam with “C” Cross section
2. ### Based on equilibrium conditions

1. Statically determinate beam – For a statically determinate beam, equilibrium conditions alone can be used to solve reactions.
2. Statically indeterminate beam – For a statically indeterminate beam, equilibrium conditions are not enough to solve reactions. Additional deflections are needed to solve reactions.
3. ### Based on the type of support

1. Simply supported beam
2. Cantilever beam
3. Overhanging beam
4. Continuous beam
5. Fixed beam

## Different types of Beams based on the type of support

1. Simply supported Beam : A type of beam which is supported at both ends  is called as Simply supported beam. It is the one of the simplest structural elements in existence.
2. Cantilever Beam : A type of beam which is fixed at one end and free at the other end is called as Cantilever Beam.
3. Fixed Beam : It is a type of beam which is fixed at both ends is called as Fixed beam.
4. Overhanging Beam : A beam having its end portion extended beyond the support, is known as overhanging beam. A beam may be overhanging on one side or on both sides.
5. Continuous Beam : A Beam having more than two supports is known as continuous beam.
