Weight Capacity

  1. Nov 3, 2015 #1
    I am trying to determine the weight capacity of a steel storage shelf i am making. The shelf will be 119in long with a 10in upright every 37in. The shelf will be made out of 2x2x1/4 HSS. In order tod etermine how much it can hold, do i determine how much each 10in column can support with a force straight down?

    if doing that i determined the reactions at each upright for one side,

    R1= 2/5WL
    R2= 1.1WL
    R3= 1.1WL
    R4= 2/5WL

    W= max uniform load applied (unknown)
    L= length (37in)

    Just curious if im doing this correctly or if im forgetting about something.

    thanks in advance!!

    What's the width of this shelf?

    In addition to the max load the supports can handle, you should also check the bending/shear stresses in the horizontal supports as well.
    With such a short support length (10"), buckling of the supports may not be the limiting factor in determining the max. load.

    14" wide.

    Also i thought of that as well but its been a long time since iv done stuff like this which is why i wanted some advice.
    How would i determine my max bending/shear stress?
