Fall Peotection
Fall Peotection
(OP)
For a 5000lb fall protection load, is that also lateral or just vertical?
For a person falling over the edge, what amount of eccentricity do you use for torsion on the beam?
Thanks

2. That is in any direction in a 360 sphere, use engineering judgement to figure out the critical direction Shear, Bending, Axial Tension.
3. Eccentricity is whatever the height or length of the anchor. Where does the person attach to?
RE: Fall Peotection
It’s an eye on a small column on top of the beam. The any direction answers my eccentricity question, it seems 5k left/right will impart a torsion on my beam.

3600#3100# live load, which works out to 5,000# factored load.I generally don't consider these to be "any direction" but rather, any direction where a fall load could occur.
For a typical rooftop application, that likely means a horizontal load in any direction. For a typical platform/tank access, that probably means a load downward around 45 degrees. I`ve never applied this load upward.
RE: Fall Peotection
**Live load = 3 100lbf for each attached lifeline in every direction that a fall arrest load may be applied
You can also refer to IBC 2018 1607.10.4
**Live load not less than 3 100lbf ... in every direction that a fall arrest load can be applied.

RE: Fall Peotection
I`m not sure that I follow your interpretation of the directionality.
Did you highlight "EVERY DIRECTION" to mean that you think a load applied straight up would be appropriate?
I consider the latter half of that sentence to indicate that isn't necessary, and a fall arrest load couldn't be applied upward.
RE: Fall Peotection
The "every direction" is included in the clause of the code. Just something I wanted to point out to OP, so the design isn't limited to one particular scenario in case there's a possibility for other scenarios. I always consider "straight" and "non-straight", say "biaxial" to capture different limit states.
