SCF for compressive stresses

SCF for compressive stresses

SCF for compressive stresses

(OP)
I have a beam made from a square box section with drainage holes in the bottom flange. With bending of the beam we have compressve stresses in the bottom flange. What kind of SCF do I have to calculate around these holes. I have looked through my Peterson, but can find no mention of SCF for Compressive stresses. Appreciate any feedback from you experienced structural guys

RE: SCF for compressive stresses

Good morning izax1,

I'm thinking there won't be one for compression. Generally the stress concentration is looking for a condition where failure would initiate from a crack, not yielding. You won't get that sort of failure in compression with steel. But if you have a condition where the load can reverse then you could have something to consider. I don't have reference to share but some one with a better understanding of fracture mechanics (maybe a materials guy?) can point you in the right direction.

regards,
Michel
