Thank you all for the valuable input! I do realize material properties and section properties are not the same and I guess I should've chosen my words more technically. I appreciate the input from all of you

I agree with your statement about empirical observation. Maybe I will initiate a study with some colleagues.

Yeah jdonville that is something I was already planning out for certain areas where the rust is a little concerning. Thank you all for your insight! If you come across any studies/equations I can read over just let me know.

Thank you both for the insight. So if you have a metal staircase with corrosion covering roughly 70% of it, is it safe to assume zero strength for the staircase and to not allow access through it? I seem to get pushback on that assumption, but I don't see it as an unreasonable assumption. I...

Are there any good sources/articles/studies done on the effect that rust/corrosion has on a material's strength? Specifically, I am interested the effect that rust has on a metal's strength, and if there are any equations that exist to determine the strength after a certain amount of...

Thank you all for your help/assistance!

JLNJ, thank you. I have requested any test reports from the manufacturer. I do not have much experience with concrete anchors, but from research I've done online and what I've learned, concrete anchors can have a high pull-out force. Are there any specific analyses I can perform to ensure the...

Just looking for some professional engineering judgement. The attachment below is a Concrete Anchor Screw for fall protection purposes; however, I find it hard to believe that it would stay in the concrete under the loading of a fall. My judgement is telling me that if it was installed into...

CANPRO, I agree. Fall protection anchors that receive an impact load should be reanalyzed, while the rest of the fall protection equipment (harness, lanyard, connectors, etc...) shall be taken out of service.

@CANPRO and @human909 I understand how, for horizontal lifelines, the force translated to the anchor can be greater than 5000lbs due to the geometry; however, in a simple fall arrest system (full body harness, 6' energy absorbing lanyard with an average arresting force of 900lbs, I-beam clamp)...
