Anchoring to reinforced masonry for fall arrest
Anchoring to reinforced masonry for fall arrest
(OP)
I'm looking to design a fall arrest anchor in reinforced CMU wall using a swivel "d-ring": http://www.fallprotectionpros.com/guardian-mega-sw...
It is not specified to be used in CMU. However, we are looking to use it in a reinforced CMU wall that has achieved compressive strength of over 5,000 PSI in a prism test. The guardian D-ring requires 3,000 PSI concrete. Does this make it acceptable to use a grout-fill CMU wall? Or does grout/masonry block behave differently than concrete? I don't have alot of experience with masonry.

Can anyone share insight on anchoring into masonry (reinforced)for fall arrest?

I think the concrete stress frustum and breakout area will be challenged with the CMU/grout interface. If I was going to use this anchor with this wall, I would through-bolt it through a solid core with reinforcement using the backplate.
