What is the Difference between a Plinth Beam & Ground Beam?

Plinth Beam

  • Plinth beam is a beam in a framed structure provided at ground level.
  • It also known as a tie beam because it binds the column.
  • So it reduces the length of column and slenderness ratio.
  • It may not carry any slab load and designed to carry its own self weight and masonry load above the plinth beam.
  • The plinth beam needs to be strong, but need not to be made up of reinforced cement concrete (RCC) all the time.
  • It provides additional stability in regard to settlements of the building and earthquake damages.

Why Plinth beams are used?

  • To avoid differential settlement.
  • To maintain the plinth plane proper.
  • To connect all the columns if depth of foundation is high.
  • To avoid difficulties in construction of walls.

Ground Beam

  • A ground beam is constructed at foundation level.
  • It support the wall or joist, if the soil sub grade have poor bearing capacity.
  • It is mainly Reinforced Cement Concrete Beam.

Why Ground Beam is Provided?

  • To prevent settlement of wall.
  • It indirectly increase the bearing capacity.
