What is the plinth beam size for 2, 3 and 4 storey house? Hi guys in this article we know about plinth beam size for 1 storey (G+0) house | plinth beam size for 2 storey (G+1) house | plinth beam size for 3 storey (G+2) housea | plinth beam size for 4 storey (G+3) house & minimum size of plinth beam according to IS code 456.
When we go through the plinth beam design we should mention following point: 1) the possible distance or span and depth it all depend on load to which the beam is subjected, 2) plinth beam size depend on amount of load on the column acting on it by beam and RCC slab, 3) many axial and Lateral load acting on beam, 4) large span greatly influence the bending moment on beam, 5) Thumb Rule for plinth beam design are appropriate for very small project like G+1,G+2 & G+3 Building and 6) plinth beam design for building construction it depend on many factors like topography, whether and size of building.

In this article, we will go through the essential thumb rules to be followed for giving a plinth beam layout. Ofcourse plinth beam have to be designed in accordance to the total forces acting on the structure, but apart from that, it is essential for every Civil engineer and Architect to remember a few thumb rules so that they are prevented from making mistakes.
Three thumb rules for design of plinth beam to be followed are as follows:1) height of structure, 2) clear span between column, 3)Alignment of columns and various load applied on it.
The size of the plinth beam depends on the total load on the beam. There are axial loads and lateral loads. Large beam spans induce bending moment not only in the beams, but also in columns which are pulled by the stresses in the beams.
What is the plinth beam size for 2, 3 and 4 storey house?
Usually width of the beam is kept as 9″ or 225mm because, the width of wall is 9″ in India. So that the appearance of the structure will be good.
What is the plinth beam size for 2, 3 and 4 storey house? minimum size of an RCC plinth beam should not be less than 9”x 9” (225mm x 225mm), according to general Thumb Rule, for 1 storey building size of plinth beam is 9”x 9” (225mm x 225mm) and 9”x 12” (225mm x 300mm) plinth beam size is used for 2 storey (G+1),3 storey (G+2) and 4 storey (G+3) house.
