How to determine steel strength formulas

  1. Nov 2, 2012 #1
    not sure if I am in the right place or not but nevertheless need some help

    I am trying to figure the correct steel to use for sign support.
    I am trying to determine if a 5 x 5 inch with .25 wall is as strong or stronger than a 6 x inch tube with a 3/16 wall. Can't find any formulas to help me out.

    thanks

    Check out the AISC Steel Construction Manual 14th edition.

    It usually governs for steel design/capacities in the public works arena.

    You will need to be a lot more specific if you want a useful response.
