How to determine the 5000 lbs strength of anchorage point?
How to determine the 5000 lbs strength of anchorage point?
(OP)
Hi all,
I am new here. I have read a lot regarding the anchors and anchorages here but couldn't find the answer to my question.
I want to know how to determine the 5000 lbs strength of anchorage points. What is the calculation to determine that?
We are now designing fall protection system for the roof workers. We will fix scaffold tubes to the I-beams and pass the horizontal lifeline through the eyes on the scaffold tubes. How can I make sure that it meets the requirements?
Thanks.

If you're fixing tubes to the steel beam and then the lifeline to the tubes, why not just attach the lifelines directly to the beam?

I'll dabble in a lot of things, but for that I don't just want an SE, I want one with experience working on them.

But maybe that's all you need for your application. I think you need to take a step back and first determine exactly what it is you need and what you're trying to achieve with this.

OSHA requires the 5,000 lb strength, but there's no guarantee that there's anything in the vicinity to actually anchor to, and that's part of the challenge.
OSHA also allows that load to be reduced where you can show that fall-arresting lanyards will limit the force, and that'd be a major factor on a design like this where available strength may be limited.

The cantilevered red and white striped posts are held on how?
To what what steel underneath?
To try to hold who? (How many? at what weight?)
I'm assuming the loops on the red-and-white poles are for "wire ropes" to act as the lifelines or as the guard rails?

For fall protection, I never factor the 5000 pound design load. I assume 5000 pounds is the limit state and compare it to the structure's nominal resistance times phi.
