Help on sizing a steel I-beam for garage 36ft span for a 3000lb capacity

[WeldEng0318]

Hi,

I'm not a structural engineer. I went to school for welding engineering and in my statics and strength of materials course we did discuss something along the lines of this.
I have a span of 36ft that I am trying to figure out what size I-beam I would need to support 3000lb. I know there was a formula to get this figure I just can't remember or find it. Any help would be appreciated. The 36 ft beam would be welded to 2 uprights say 1/4" 4x4 sq tube and the tubing would be anchored into the concrete.
I do not have access to Solid works as my work primarily consists of using Codeware Compress and building ASME pressure vessels but I do remember doing FEA analysis on similar stuff like this.

Thank you

Hire a local structural engineer.

There's a lot more than one formula. How is it braced? Where is it braced? What is the capacity and stiffness of the braces and their connections? Is that a point load or a uniform load? If a point load, where is it? Is it movable? Could there be impact involved? How sensitive is it to deflection? What are the depth restrictions. Etc. Etc. Once those questions are answered, then the correct formulas could be selected and the beams sized appropriately. For something like that, you really should have a local structural engineer design it for you.

Okay great thank you! Its going in a garage to hoist like an engine drive welders, other heavy parts, but I figured its a little more complicated than just one formula which is out of my expertise so hiring a structural engineer is what I will do.

Thanks for the quick responses.
