How to calculate weight of i beam / How to find weight of i beam, in this topic we will learn about how to calculate weight of i beam. Today an engineer use i beam widely in construction forming of column and beam and many types of different structure having different length size and dimension.
The i beam mostly look like as H shaped beam and also called as wide beam and universal beam.
Different full form ISMB, ISMC, ISJB, ISLB and ISWB related to i beam
In structural engineering of Steel and building construction technical terms is used for i beam by engineers that is ISMB, ISMC, ISJB, ISLB and ISWB
◆Different full forms
1) ISMB- Indian Standard medium weight beam
2) ISMC – Indian Standard medium weight channel
3) ISJB – Indian Standard junior beam
4) ISLB – Indian Standard light weight beam
5) ISWB – Indian Standard wide flange beam

What is i beam?
Mostly I beam having H shape consists of two horizontal plane part that is known as flange which is connected by one vertical component that is known as web.
Both shape of flange and web create its I shaped cross section of Steel and beam. It has many application in building framing, bridges and structural engineering purpose. It is shape of choice for structural Steel buildings, the design and structure of the i beam makes its unique and capable of handling variety of loads acting on it. Now we discuss about how to calculate weight of i beam.
How to calculate weight of i beam
ISMB (Indian Standard medium weight beam) weight calculation formula

ismb 400×100×8.8:- ismb size 400mm × 100mm × 8.8mm have weight 15.274kgs/feet or 50.1kgs/meter.
ISMB full form:- full form of ismb is Indian standard medium weight beam.
ISMB 200 weight:- Indian Standard medium weight Beam 200 weight per meter is 25.40kgs/m, their cross sectional area is 32.33cm2, depth of section 200mm, width of flange 100mm, thickness of flange 10.80mm and thickness of web is 5.70mm.
We have given:-
◆ flange (A) component
Flange length = 100 mm
Flange thickness = 15 mm
Height of flange = 1000 mm
◆ web ( B) component
Length of i beam = 200 mm
Thickness of web = 15 mm
Height of web = 1000 mm
Density of steel = 7850 kg/m3
Now we have to calculate volume of both flange and web
Now volume of flange = l×b×h
Volume of flange = 100×15×1000 mm
We should convert into metre we get
Volume of flange = 0.1×0.015×1 m3
Volume of flange = 0.0015 m3
In given figure we have two flange of equal volume so we should multiply by 2 in volume of one flange
Volume of flange = 2×0.0015 m3
Total volume of flange = 0.0030 m3
Now we should calculate volume of web
Volume of web = l × b× h
Length of web = 200 mm – thickness of two flange
Length of web = 200 – (2×15) mm
Length of web = 170 mm
Volume of web = 170×15×1000 mm
Now convert into metre
Volume of web = 0.17×0.015×1 m3
Volume of web = 0.00255 m3
Now we have to calculate total volume of i beam that is sum of volume of flange and volume of web
Total volume of i beam= 0.0030+0.00255 m3
Volume of i beam = 0.00555 m3
Now we have to calculate weight of I beam that is equal to multiplication of density of steel and volume of i beam
Weight = volume × density
Weight = 0.00555 m3×7850 kg/m3
Weight = 43.57 kg
Hance weight of i beam for given dimension is approx 43.57 kg
