What is a Burke-Loop?
What is a Burke-Loop?
(OP)
I'm currently retrofitting a building from 1983 and it has called out on the roof framing details a " 3/4" Diameter Burke-Loop (404-No-035)". Basically it's used horizontally in the anchor bolt slot of an HD-2 to connect a roof purlin to a concrete tilt-up wall. Does anybody have knowledge of these things because I've never heard of them before. Basic load info is what I need since we're trying to verify if the existing ties can take the current required anchorage forces.

It sounds like a coil lifting insert to me. See the below catalog pdf starting on page 234 for examples:

The model numbers are completely different now though. Your best bet would be to give them a call and see if they can provide any historical data.
