Framing Angle - 1 bolt each leg
Framing Angle - 1 bolt each leg
(OP)
Can experienced wood designers please comment on the acceptability of this connection.
Basically I have a preexisting suspended ceiling which has worked for the last ten years. Myself and a builder where walking on this ceiling and it was certainly strong.
Being asked to certify the existing structure, I have investigated the structure and found the existing connection to consist of 2-skewed nails. Doing the calculations, I did not feel this connection had the required capacity so have specified framing anchors with 2-bolts each leg. I only received one bolt each leg.
I can justify to myself that this connection can work transferring shear with bearing on the wood.
Would this connection detail be acceptable to most?
All comments are appreciated.
Regards

A lag screw might work in the ledger beam, but it would split the end of the joist member. I would drill and use a bolt there. Bolts generally have a little more cap'y. than lag screws. Is this the same ceiling as had the bent .25" hanging rods from a purlin web?

Also, don't get lulled into thinking that something is "design" strong just because it didn't move under your weight. You're thinking like a contractor...think like an engineer....it hasn't yet seen its design loads.

Good pick up. It is the same ceiling.

If I understand the relationship of the two members, I would not be concerned with the edge distances as it appears to me that it could be adequate for the bolt size seen. However, the built-in entricity of the connection concerns me. It will induce horizontal splitting with time.
