Stress Concentration of Hole through HSS
Stress Concentration of Hole through HSS
(OP)
Does anyone have any reference material on how to determine the stress concentration of a hole in HSS tube. To give you an idea what I am working with, I have an HSS tube fixed at both ends with a 7 ton Eye bolt fastened through a hole in the center of the HSS tube.
Any information would be great.
Thanks.

Have you checked Peterson's book?

No I have not checked it. I will see if I can track it down. Most books I have checked have stress concentration for rods and plates but no structural steel.
RE: Stress Concentration of Hole through HSS
does the eye-bolt attach to the tube ? or does it pass thru the tube and is secured by a nut ?? (i'm picturing the tube being horizontal, like a beam, and the eye-bolt applies a vertical load).
RE: Stress Concentration of Hole through HSS
The eye bolt passes through a hole drilled through the HSS tube which is fastened with a nut from the top. The eye-bolt is supporting a vertical load. I also don't believe this hole will have a significant stress concentration but I need to justify my assumption.
RE: Stress Concentration of Hole through HSS
Assuming I understand the problem I don't believe that (see) there is any stress concentration from this setup....You should check for local deflection of the top of the section, contact stresses, bending stresses, and vertical shear stress in the region outside of the local area (this is the same type of failure that occured in the Hyatt in Kansas City)
