Stress Concentration
Stress Concentration
(OP)
Hi All,
I have the following problem - I have an I-beam. This I beam is replaced with e new I beam, same material, but the middle of the beam is beefed up, which is a stress concentration. Any hints, how should I get away with the new design, addressing the fact that I have a higher stress concentration? Main load of the beam is tension/compression.
Thank you all in advance,

the beefed-up section is designed for the higher loads at the mid-span, right?
you also need to check the un-beefed-up section, where the loads are highest
i guess you can look into the stress concentration effect ... i'd've thought your in-service loads would be so low that you were near the endurance limit of your steel. you wouldn't combine stress concentration with static design loads, right?

are you looking at the Kt due to hole or at the beefing up transition ? at either location it should be easy enough to calc the stress from bending, and to pick a Kt from somewhere.
