Plinth Beam and Tie Beam : Difference Between Plinth Beam and Tie Beam, Purpose of plinth and tie beam

  Plinth Beam and Tie Beam : Difference Between Plinth Beam and Tie Beam

Here you will find the difference between Plinth Beam and Tie Beam. First of all we will know what is plinth beam and tie beam. Then we will know the purpose of using the plinth beam and using the Tie beam. And then we will differentiate the plinth beam and tie beam.

 

Plinth and Tie Beam

Plinth Level

It is the level where the sub-structure ends and the superstructure starts. In a simple word it is the topmost level of the ground.

What is Plinth Beam?

Plinth Beam

The beam which is provided at the plinth level is called plinth beam. In framed structure plinth beam is the first beam constructed after foundation.

Purpose of the Plinth Beam

1.       To distribute the load of walls over the foundation.

2.       To connect all the columns.

3.       To prevent cracks from the foundation wall.

4.       To avoid differential settlement. 

What is Tie Beam?

Tie Beam

It is also known as general beam that we call normally. The beam which connects two or more columns/rafters in a roof/roof truss or in any height above floor level is called tie beam. Tie beams are mainly provided in roof truss and at the plinth level. These beams do not convey any floor loads and only acts as length breaker for columns where the floor height is unusually high.

 

Purpose of Tie Beam

1.       To carry axial compression.

2.       To transfer the rafter’s load to the column.

3.       To prevent columns from buckling.

 Difference Between Plinth Beam and Tie Beam

The difference between plinth beam and tie beam is that actually, there is no difference between them. Tie beam is also a type of plinth beam. When tie beam is provided at the plinth level it is known as plinth beam. That means the only difference is the height at which they are provided.

                Plinth beam is only provided at plinth level but tie beam is provided anywhere above the plinth level and floor level. And we can also say that the height makes the difference because it also can be known and called that the beam made above the plinth level it is called tie beam and the beam made at the plinth level is called Plinth beam. In any structure the first beam we construct is Plinth beam.

 So that’s the short and simple blog about the Plinth beam and Tie beam. All the things are written in very simple language so anyone can understand this.
