Safe Work Load of a T Beam

Hi Guys,

I want to determine the safe work load (SWL) capacity of a trestle in my workshop. It is a T Beam with width (W), height (h), thickness (t) and length (L). It is welded each end to two legs - what kind of support would this be considered as? Fixed or pin?

Can someone walk me through the calculations to find the SWL that it can endure.

I remember doing something similar in my structural analysis class but cannot find my notes, I believe i have to find the section modulas of the T beam, find allowable stress and find moment? I do not remember exactly the formulas.

There are also cleats 1/4 intervals along length (L), do I consider this in my calcs?

Thank you

Asking this question on the Internet is not a good approach. You need to talk with a professional engineer in your area, and get them to help you with the calculations. Since it sounds like you are doing something structural, you will likely need to get your local Building Department to sign off on any changes in the structure (or new loads applied to this beam), and your company's insurance company will need to sign off on the changes/new application as well.
