Formula to calculate weight of Steel I-Beams through their sizes, also please elaborate?
Answer:
if you refer to those standard I-beams theres no need for you to calculate the weight of steel I-beam, they are already tabulated according to their sizes and cross section all you have to do is to buy a AISC (American Institute of Steel Construction) Steel Handbook all the sizes and properties of steel a I-beam are tabulated here, visit www.aisc.org.
American Standards show the "weigth per unit length" of steel beams as the last number; like W100X19.3 means 19.3kg weight per meter length. If imperial units are used then the weights are in "Pounds per Foot" length. You can get total beam wweight by multiplying this with length of beam.
Otherwise, if there is some other standard for beam sections, you can yourself calculate weight by:
Weight=(cross-section area)X(Length)X(Density)
Use similar (coherent) units for above formula. Density of steel may be taken as 7900 kg/cubic meter.
