I Beam

This question has popped up several times in the forum the past few years.

Do a "SEARCH THIS FORUM", and you'll find your answer.......it's quite simple actually.......multiply the unit weight of the beam by it's length using compatible (like) units. Most steel manufacturers (and steel associations like AISC and AISI) provide tabulated unit weights of their beam products.

In U.S. AISC (American Institute of Steel Construction) terminology, a channel such as C6x20 designates two items: the 6 is 6-inch depth; the 20 is pounds per foot. This makes weight computations really easy. I don't know if typical SI representations do the same.

Rather than calculating, one simply looks it up in the catalogs of structural shape suppliers, or standard reference works.

By reference to the tables in Kempe's Engineers' Handbook, any edition?

First i apologies if i have mistake in writing.

Do the channel a standard or its welded channel hoe its not standard? Because if the channel its standard you cant use table for channel were you got weight for each tip, and if the channel its not standard then you calculate weight for itch part in the channel and to the end you give 3% from all weight for welding part.

This while give results for weight to channel.
