I beam strength formula
(OP)
Is there a simple formula to find out how much uniform weight an I beam can support. example type in the size of the beam (W8)and the span (24ft)and come up with the lbs it can support (if supported on the ends).
RE: I beam strength formula
M = Fb S
M = w L^2 / 8
solving for w,
w = 8 Fb S / L^2
where Fb is the allowable bending stress
There isn't one single simple formula for obtaining the maximum uniform load a beam can support as it depends on the support conditions. In addition, flexural stress may not be the controlling factor since for long spans, beam deflection usually controls.
Invest in a relatively inexpensive steel beam program called RAMSBeam from http://www.ramint.com/products/r_sbeam.jsp
