Load Calculation on Column:

How to Load Calculation on Column?

1. Size of column Height 2.55 m, Length = 300 mm, Width = 600 mm
2. Volume of Concrete = 0.30 x 0.60 x 2.55 =0.459 m³
3. Weight of Concrete = 0.459 x 2400 = 1101.60 kg
4. Weight of Steel (1%)  in Concrete = 0.459 x 1% x 7850 = 36.03 kg
5. Total Weight of Column = 1101.60 + 36.03 = 1137.63 kg = 11.12 KN

Beam Load Calculation:

How to Beam Load Calculation?

1. 300 mm x 600 mm excluding slab.
2. Volume of Concrete = 0.30 x 0.60 x 1 =0.18 m³
3. Weight of Concrete = 0.18 x 2400 = 432 kg
4. Weight of Steel (2%) in Concrete = 0.18 x 2% x 7850 = 28.26 kg
5. Total Weight of Column = 432 + 28.26 =  460.26 kg/m = 4.51 KN/m

How to Wall Load Calculation:

• we, know that the Density of bricks varies between 1800 to 2000 kg/m3.
• For a 9 inch (230 mm) thick Brick wall of 3.55-meter height and a length of 1 meter,
• The load / running meter to be equal to 0.230 x 1 x 2.55 x 2000 = 1173 kg/meter,
• which is equivalent to 11.50 kN/meter.

• The load/running meter to be equal to 0.230 x 1 x 3.55 x 650= 530.725 kg

How to Slab Load Calculation:

• Let, Assume the slab has a thickness of 150 mm.
• So, the Self-weight of each square meter of the slab would be
• Slab Load Calculation = 0.150 x 1 x 2400 = 360 kg which is equivalent to 3.53 kN.
• Now, If we consider the Floor Finishing load to be 1 kN per meter, superimposed live load to be 2 kN per meter, and  Wind Load as per Is 875 Near about 2 kN per meter.

• Total Column weight= 2160 + 70.38 = 2230.38 kg/m = 21.87 KN/m.

• To calculate the weight of a steel bar, you can use the formula D^2/162, where D is the diameter of the bar and 162 is a constant.
• To calculate the weight of a steel plate, you can use the formula width * length * thickness * density.
• To calculate the dead load for a steel beam, you can use the formula volume of member * unit weight of materials.
• To calculate the load of a beam from a slab, you can divide the slab into trapezoidal and triangular areas, and then multiply the segment area by the slab's unit load divided by the beam length.
