Now, as an answer to your question construction of stone/brick masonry support under plinth beams in order to provide support is not required because the load of the plinth beams will be transferred to the columns if it is designed to do so.

What is under plinth beam?
Plinth beam is a reinforced concrete beam constructed between the wall and its foundation. Plinth beam is provided to prevent the extension or propagation of cracks from the foundation into the wall above when the foundation suffers from settlement.
Is plinth beam below ground level?
Plinth Beam is a beam in a frame structure provided at ground level. Also known as tie beam because it binds the column.
Is plinth beam a substructure?
Plinth beam is an RCC member which separates the Superstructure and the substructure and acts like a tie beam that keeps columns, walls connected. And, Substructure is a structure which lies below ground level includes foundation.
Is plinth beam above ground level?
Plinth beam is provided at the plinth level above the natural ground surface where soil filling and labelling for building construction has been completed. Average height of plinth beam is kept about 1.5 feet (400mm) high from ground level.
What is done after plinth beam?
Superstructure – Column
After the plinth slab is cured then the main structure for the house is started. The columns are brought up and the frame for further construction is prepared.
Is plinth a foundation?
A plinth level forms the foundation of a house. It is a rectangular block of stone on which a column and pillar of a building stands. It is a wall between the ground level and the ground floor level.
Can we avoid plinth beam?
Yes, It is required to install a plinth beam between two columns, which used for installing an iron gate.
Which is better ground beam or plinth beam?
Constructed slightly higher than ground level, the plinth level is where the plinth beam is constructed. It helps to tie in all the columns of a structure to reduce the slenderness ratio. Usually, a minimum of 2 bars on the top and bottom, 10 millimeters wide, are used to construct it.
What is the difference between ground level and plinth level?
Difference between Plinth Level and Ground Level: A plinth level is the height of a building’s ground floor above the surrounding ground. The term ‘ground level’, or ‘ground floor’, is often used to refer to the level of a building that is actually at ground / street level.
What is the depth of plinth beam?
The depth of the plinth beam should not be less than 20cm. c. Span/Overall Depth Ratio: The span/overall depth ratio must range from 15 to 18.
What should be the size of plinth beam?
Standard Dimensions of Plinth Beam
The width of the beam is usually 9 ″ or 225mm, as the wall width in India is 9 ″. So that the structure has a good look. The minimum size of the RCC plinth beam should not be less than 9 “x 9” (225 mm x 225 mm), as a general rule of thumb.
Is plinth beam a structural member?
A beam is a horizontal structural member provided in buildings to transfer loads from the structures above to the columns, walls, and foundations. Among the different types of beams used in building construction, tie-beam and plinth beams are the two common types.
What is standard height of plinth?
between 300mm and 450mm
Plinth level is is at which the building ends and the super structure starts. The plinth height is between 300mm and 450mm from ground level. Experts suggest that the plinth height of 150mm is better to be adopted from top of the road.
What should be the average height of plinth?
about 300 to 400 mm
What should be the average height of plinth? Explanation: Generally the plinth level is provided at about 300 to 400 mm above finished ground level. It is suggested that plinth level should be decided by considering the top level of the ground and hence considering the level.
What is the ratio for plinth beam?
In the lean concrete in foundations, a cement, sand and coarse aggregate mix of 1:5:10 or 1:4:8 is used. In the damp-proof course, a concrete mix of 1:2:4 is used. If plinth beams are provided, M20 concrete is used.
Is PCC required below plinth beam?
P.C.C. work should cover the top of the plinth beam work procedure. So, when the plinth beam is in progress, level the P.C.C.
How long does it take for plinth beam to cure?
striking time for deshuttering for roof slab is 14 -21 days, column is 7- 10 days, plinth beam is 5 – 7days, lintel beam is 7-8 days, wall beam is 7-10 days and rack and slab is 5 -10 days.
Which cement is best for plinth beam?
Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength.
What are plinth foundations?
A plinth is an architectural term used to describe a heavy base supporting a column. A concrete plinth is a reinforced concrete beam that is constructed between the wall and its foundation.
How do you protect a plinth beam?
A plinth protection usually is done by pouring an approximate 75 – 100 mm layer of plain cement concrete along the edge of the building. However, in cases of buildings that are well-finished, the plinth protection can be covered with a layer of paver blocks, gravels or even the surrounding lawn.
