TJI Joists to Masonry Firewall
TJI Joists to Masonry Firewall
(OP)
Without using a firecut, does anyone know of a way to connect TJI joists to a masonry firewall??
There will be joists on both sides. If the joists fail on one side, the other side still has to support the wall laterally. Obviously if the joists fail on one side, they also can't take down the wall as well.
Any ideas??

With joist hangers there are 2 situations:
1. If the Joist is fastened to the hanger, it will damage the wall if the joist comes down.
2. If the joist is NOT fastened to the hanger, the wall will not receive the lateral support.

Fire walls can be constructed using two independent masonry walls that abut one another. The TJI joists from one side frame onto only one of the masonry walls and vice versa for the other side. Fire in one compartment could result in collapse of one set of the TJI's and attached masonry wall, however, the fire separation of the other wall will remain intact.
You could also look at fire rated stud walls on each side of the masonry fire separation that would provide support for the TJI's, independent of the masonry fire wall.
There should be a ULC or Code approved detail for your area that details this situation.

Both good ideas that I have considered, but the bulk of the building design has been completed and construction of the foundation has started. So unfortunately, we can't add another masonry wall or stud wall.

I contacted Simpson and they don't have anything that will meet my criteria.

Is there some facet of the masonry firewall that I'm not catching onto that will prohibit this solution?
