How do you calculate load on a plinth beam?

Load Calculation of Beam

1. 300 mm x 450 mm excluding slab thickness.
2. Concrete Volume = 0.3 x 0.60 x 1 =0.138m³
3. Concrete weight = 0.138 x 2400 = 333 kg.
4. Steel weight (2%) in Concrete = = 0.138 x 0.02 x 7850 = 22 kg.
5. Total Column weight= 333 + 22 = 355 kg/m = 3.5 KN/m.

How do you calculate concrete for a plinth beam?

Calculation of volume of concrete for the column:

1. Volume of Concrete = 0.6×0.4×3= 0.72m3
2. Volume of Circular column = πr2 x 3 = 3.14 x 0.252 x3 = 0.58m3
