Concealed Flange Hangers 1

[XR250]

How do y'all feel about these types of connections at the end of the beam? The capacity does not seem to be reduced in the Simpson tables. Seems like fastener end distance would be an issue.

The set up of the test assembly effectively eliminates one potential failure mode, tearing /splitting of the bottom fibers of the carrying beam. For comparison of relative capacity, assuming they use the same rig setup for a conventional installation, the rig results for the end condition would be useful. But for actual capacity I'd say not so much.

In my world (commercial/institutional wood framing) 1600 lbs is pretty light. I've specified HUC's in this configuration many times for much higher loads and I'm not losing any sleep. The concern about splitting is a valid one, especially if the carrying member is existing which is why I generally spec these as HUCQ which includes the SDS screws (which tend to reduce splitting) and the hanger has higher load ratings.
