Introduction
We have looked into types of beams with respect to the materials used for construction in the earlier article. In this article, we will be looking into types of RCC beams with respect to support type.
Definition of Beam
Beams are horizonBeams are horizontal structural members which transfer loads horizontally along their length to the supports. Eventually, the loads are resolved into vertical forces through the column. When the load is applied to the beam, it causes bending moments and shear forces along their length. Thus, beams are used for resisting vertical loads, shear forces and bending moments.
Types of RCC Beam
RCC beams are classified into the following categories with respect to their support type: –
- Simply Supported Beam
- Fixed Beam
- Cantilever Beam
- Continuously Supported Beam
- T-beam
Simply Supported Beam
In this type of beam, the ends of the beam simply rest on the supports provided. This type of beam is called a simply supported beam or is sometimes as freely supported beam. This type of beam is usually seen under the bridge deck.
Fixed Beam
A beam is said to be fixed when it’s both ends are fixed or set. It is sometimes called as built-in beam. The end or support of the beam is restrained, which means its support is anchored or not allowed to move.
Cantilever Beam
When one end is free and the other end is fixed it is called as Cantilever beam.
Continuously Supported Beam
When the beam is provided with more than two supports it is known as a continuously supported beam. This type of beam is a single beam which has intermediate support either provided by the column or wall.
T-Beam
When the floor slab and beam running along the slab are attached as a single member it is called a T beam. The casting of the beam and slab must be done simultaneously to form a monolithic structure. T-beam can be either regular or inverted T-beam.
