I am struggling to remember how to determine the allowable delta max for a beam.(adsbygoogle = window.adsbygoogle || []).push({});

I am currently modeling the bending forces upon a piece of square tubing, and though developing delta max seems rather straight forward, I can not seem to remeber how to determine just how much deflection I am allowed in that beam.

Essentially... I have my delta max, but how do I know if that much deflection is OK in my design (failure due to Plastic Deformation)

Any input is appreciated

I have seen on another PF thread that 1" of deflection per every 250" of beam is an accepted approach. Is this accurate? What is the basis behind this estimation?

Thanks
