Sketch a G+1 residential plan according to Vaastu Shastra and Calculation of Loads as per IS code
Different load calculation on column,beam,wall & slab
*Column = Self Weight x Number of floors
*Beams = Self Weight per running meter
*Wall Load Per Running Meter
*Total Load on Slab (Dead Load + Live Load +Wind Load + Self-Weight)
Besides this above loading,the columns are also subjected to bending moments that have to be considered in the final design. These tools are reduced laborious and consuming method of manual calculations for structural design, this is highly recommended nowadays in the field.
The most effective method for designing structure is to use advanced structural design software like STAAD Pro or ETABS. For professional structural design practice, there are some basic assumptions we use for structural loading calculations.
Load Calculation on column:
We know that the Self-weight of Concrete is around 2400 kg/m3, which is equivalent to 24.54 kn/m3and the Self-weight of Steel is around 7850kg/m3. ( Note: 1 Kilonewton Is Equal to 101.9716 Kilograms)
So, if we assume a column size of 300 mm x 600 mm with 1% steel and 2.55 (why 2.55 so, 3 m column hight – beam size) meters standard height, the self-weight of the column is around 1000 kg per floor, that id equal to 10 kN.
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:
We adopt the same method of calculations for beam also.
we assume each meter of the beam has dimensions of 300 mm x 600 mm excluding slab thickness.
Assume each (1m) meter of the beam has dimension
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
So, the self-weight will be around 4.51 kN per running meter.
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 2.55-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.
This method can be adopted for load calculations of Brick per running meter for any brick type using this technique.
The load/running meter to be equal to 0.230 x 1 x 2.55 x 650= 381.23 kg
if you are using these blocks for construction, the wall loads per running meter can be as low as 3.74 kN/meter, use of this block can significantly reduce the cost of the project.
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.
So, from the above data, we can estimate the slab load to be around 8 to 9 kN per square meter.
Load Calculation column Beam wall slab
Load Calculation on Column:
*Volume of Concrete = 0.23 x 0.60 x 3 =0.414m³
*Weight of Concrete = 0.414 x 2400 = 993.6 kg
*Weight of Steel (1%) in Concrete = 0.414x 0.01 x 8000 = 33 kg
*Total Weight of Column = 994 + 33 = 1026 kg = 10KN
Wall Load Calculation:
Density of brick wall with mortar is about ranging between 1600-2200 kg/m3. So we consider self weight of brick wall is 2200 kg/m3 in this calculation.
1)Volume of brick wall: Volume of brickwall = l × b ×h, Length = 1 meter, Width = 0.152 mm, Height of wall = 2.5 meter, Volume = 1m× 0.152 m× 2.5 m, Volume of brick wall = 0.38 m3
2)Dead load of brick wall: Weight = volume × density, Dead load = 0.38 m3 × 2200 kg/m3, Dead load = 836 kg/m
3)It will be converted into kilo Newton by dividing with 100 we will get 8.36 kN/m
4)So dead load of a brick wall is about 8.36 kN/m acting on column.
Beam Load Calculation:
300 mm x 600 mm excluding slab thickness.
*Volume of Concrete = 0.30 x 0.60 x 1 =0.18 m³
*Weight of Concrete = 0.18 x 2400 = 432 kg
*Weight of Steel (2%) in Concrete = 0.18 x 2% x 7850 = 28.26 kg
*Total Weight of Column = 432 + 28.26 = 460.26 kg/m = 4.51 KN/m
Column Load:
A column is an essential structural member of the RCC structure that helps transfer the superstructure’s load to the foundation. It is a vertical compression member subjected to direct axial load and its effective length is three times larger than its least lateral dimension.
Dead Load Calculation for a Building:
By calculating the volume of each member and multiplying by the unit weight of the materials from which it is composed, an accurate dead load can be determined for each component.
Column Design Calculations:
*Volume of Concrete = 0.23 x 0.60 x 3 =0.414m³
*Weight of Concrete = 0.414 x 2400 = 993.6 kg
*Weight of Steel (1%) in Concrete = 0.414x 0.01 x 8000 = 33 kg
*Total Weight of Column = 994 + 33 = 1026 kg = 10KN
Footing Load Calculations:
For a 6″ thick wall with 3 meter height and 1 meter length, the load can be measured per running meter equivalent to 0.150 x 1 x 3 x 2000 = 900 kg which is equivalent to 9 kN/meter. The load per running meter can be measured for any brick type by following this method.
Concrete Slab Load Calculations:
*Size of Slab Length 3 m x 2 m Thickness 0.150 m
*Concrete Volume = 3 x 2 x 0.15 =0.9 m³
*Concrete weight = 0.9 x 2400 = 2160 kg.
Steel Load Calculation:
*Size of Slab Length 3 m x 2 m Thickness 0.150 m
*Concrete Volume = 3 x 2 x 0.15 =0.9 m³
*Concrete weight = 0.9 x 2400 = 2160 kg.
*Steel weight (1%) in Concrete = 0.9 x 0.01 x 7850 = 70.38 kg.
*Total Column weight= 2160 + 70.38 = 2230.38 kg/m = 21.87 KN/m.
Calculate Load on Beam:
*300 mm x 600 mm excluding slab.
*Volume of Concrete = 0.30 x 0.60 x 1 =0.18 m³
*Weight of Concrete = 0.18 x 2400 = 432 kg
*Weight of Steel (2%) in Concrete = 0.18 x 2% x 7850 = 28.26 kg
*Total Weight of Column = 432 + 28.26 = 460.26 kg/m = 4.51 KN/m
