Fall protection proprietary system anchorage to metal roof deck
Fall protection proprietary system anchorage to metal roof deck
(OP)
Who has experience with the anchorage of a fall protection proprietary system to metal roof deck?
I am working with a manufacturer, Guardian, with their system "XS Horizontal Lifeline system". I was provided the design load by their engineers. The load is 3,600 lbs applied horizontally to the top of a 8 1/4" post. Their system provides the anchorage of the post to the metal deck (in my case 20 ga wide rib roof deck) via their "toggle fastener".
Their sales literature says the load is "so slight", but I dont consider 3,600 lbs slight. I can easily check the roof framing for the load, but the localized effects of the load on the metal deck is not so easy, especially in the weak direction. I'm sure the manufacturer verified the ability of steel decks to sustain that type of load through full scale testing, but they are not offering it for DOR's use.
I'm sure I'm not the first one to challenge their system's anchorage scheme. What am I missing?
Thanks for your input.

Best of luck

Check out the lines in their spec in section 1.05. We generally try to be stronger than the threaded rod and then understand that insulation will crush / deck will deform / etc. to dissipate energy.
Hope that helps.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
