How to Calculate the Area of formwork required for a Beam? Calculate the area of the formwork required for a beam of 2 m span and cross-section dimension of 400 mm x 200 mm?
As far as what they do there is no difference, and both support weight loading above them. Shape wise a lintel is usually flat compared to the curved shape of an arch. Strength wise the arch is far superior and only compresses more the greater the loading, compared with a lintel that has limitationsRead more
As far as what they do there is no difference, and both support weight loading above them. Shape wise a lintel is usually flat compared to the curved shape of an arch. Strength wise the arch is far superior and only compresses more the greater the loading, compared with a lintel that has limitations to what it will hold before failing due to compression.
Having said that most lintels carry very little weight anyway as it is spread out through the interlocking of stone, block, or brick and the only weight it actually carries can be measured by drawing a line at 45° from each end of the lintel until they cross in the centre above it and what its actual loading is. Beyond that, the wall supports its own weight and that above it providing something supports the interlocking material and how the Victorians managed to support mass weight purely on timber lintels only 3 inches thick. With lintels, span becomes an issue very quickly much less so with an arch

Formwork shall be measured in square metres as the actual surfaces in contact with the concrete
The formwork or shuttering quantity for the member is measured as per the code of BIS – IS 1200:1982, Part 5- Method of Measurement of Building and Civil Engineering Works.
For Column follow the process
1. Measure the four sides of column at base or in cross-section.
2. Calculate the perimeter of column base.
3. Measure the Colum height.
4. Multiply the perimeter of base and height of column to give the shuttering area of column.
Or other way, add all 4 sides and multiply it by height of column.
For Beam follow the process
1. Take the cross-section of beam and measure the lengths of the two sides and base of beam.
2. Sum the three measurements.
3. Measure the span of the beam
4. Multiply the span length by sum of the three measurements (beam base two vertical sides) gives the shuttering area of beam.
The top side in cross-section of beam is not considered as it will be part of beam.
Or the other way, add the beam height(2 sides) and beam base and multiply it by beam length.
Other important factors to be considered while picking the shuttering quantities.
Answer:
Calculation:
Cross section I terms of metres (400
200 mm) = 0.4 
0.2 m
Width and depth are given in cross section
Area of the framework = (2
0.4 
2) + (2
0.4 
0.2) + (2 
0.2)
= 2.14
Result:
The area of the formwork is = 2.14
