I was wondering if anyone could help me size a wide flange steel beam for my shop, or point me to a web site that would help. It needs to span 36' with a concentrated load of around 3,000lbs. The load might not be at mid span. It is for a chain hoist for the jeep. There will be no other loads on it. Any help would be greatly appreciated.

I apologize if this should be in chit-chat, but I see more shop questions asked and answered here.

thanks.

A good bet would be to contact the chain hoist manufacuter. sometimes they have a maximum flange width which will make the beam depth have to be great etc... They should be able to give you guidance on what size beam vs weight required vs which chain hoist they recommend for the application.

The other thing is that the beam itself will be rather heavy not to mention the 3000 lb + load so the wall/support better be pretty strong.

For what it is worth.......

What exactly is it that you intend to lift? Lame is correct, you want a "S" beam and not a WF due to the shape of the flange. If you can find a copy of Load and Factor Resistance Design put out by the AISC all the info you need will be in there. My other question is how do you intend to support this beam? Are you gonna use 2 or maybe 3 columns? or maybe connect to a concrete wall with an end connection? or maybe anchor it to the existing structure above, like from a truss or something? That is a pretty long span if you want to stay with a relativly small beam. Do you have height limitations that need to be considered?

Thanks for the info. 2x studs packed out underneath the beam, to a concrete stem wall or footer, will support it. A buddy has this in his two car garage that we hang 1/2 the jeep from with chains. It makes for a great place to do suspension work under the jeep with nothing in the way. I only said hoist to try and make it easier to understand. I am trying to figure out if it is feasible to do this without any columns. Height is not that much of an issue. I should have at least a 10' ceiling when this is finished.

an engineering debate?!?

that bieng said,

with a 3k load, anda 36ft. span, you need a decent sized beam.

on a 36ksi beam, you need to pick an S-section with a section modulus of at least 17-ish in^3. An S8x23 should work, but it's on the shy side. An S10x25 is REALLY safe.
you can use a lighter beam if you ask for 50ksi steel, but it tends to be a bit more expensive.

Bwahahahah:D

Jackass:flipoff2:

carry on.

Thanks guys, your the greatest:D :beer:

I ordered an s10x35. For a few bucks more, bigger is better :flipoff2:

36ksi beam? Yield orTensil ksi? :flipoff2: Maybe you mean A36? You would be better off with a A572/50 or a A992. :flipoff2:

Actually,
I meant M270:flipoff2:
