Steel joist connection to CMU wall
Steel joist connection to CMU wall
(OP)
Where can I find standard details for the following roof-to-wall connections:
1. Steel bar joist bearing on CMU wall. Question: Should the embedded steel bearing plate in the masonry be flush with the top of CMU, or should the top of plate be slightly above the CMU so that the joist bearing is completely on the steel, not on the CMU?
2. Steel roof deck diaphragm connection to non-loadbearing steel stud wall sheathed with OSB. The steel joists run parallel to this wall and I need to connect the diaphragm to this wall, as this wall is one of the main shear walls of the building. One twist: the steel joists are sloping at 1/2" per ft., while the top of wall is held horizontal.

RE: Steel joist connection to CMU wall
Regarding your second question: I would allow this wall to carry the roof deck (it will now be a bearing wall), and space the adjacent joist on each side as far as possible from the wall, because the joists will deflect and the wall will not. Slope the top track of the stud wall, and weld the deck to the track.
