Forces transferred to beam and to supports from box

  1. Mar 30, 2017 #1
    Hi Guys,
    I am trying to calculate the load transferred on the beams and then to the four supports (two under each beam) from a cargo (in this case say a box) to be stored in a yard.
    I have to check the suitable beam to be used and the load transferred to each support.

    Thanks in advance. :)

    The link isn't working for me (is it for anyone else?), so could you provide the details included in it?

    As you are probably discovering, this is a statically indeterminate problem. The loads depend upon the deflections, both in the beams and in the box. You can write a vertical sum of forces equal to zero and moments in each horizontal axis equal to zero, but that only gives you three equations.

    Your options are ---
    1) Do an FEA model;
    2) Solve for force sums (e.g., the sum of the forces at the left end, rather than taking them individually)
    3) Make a group of guesses that satisfy the three equations.

    For most engineering purposes, a combination of 2) and 3) will be sufficient. If you want to get very precise, go with 1).
