Sloped deck on a level roof joist
Sloped deck on a level roof joist
(OP)
Longspan roof deck on longspan roof joists. The profile of the roof required the deck to slope perpindicular to the joist.
Is the deck required to sit flat on the joist? All i see is a 1 1/2" bearing length requirement just to prevent slip off.
Should the joist be rotated about it's long axis or instead some sort of shim welded to the top chord to provide a sloped bearing surface?

Generally, the most economic method of obtaining the slope is by varying the joist bearing elevation. The insulation thickness can be varied to achieve the slope. To weld angles to the top chord to achieve the slope is very labour intensive and costly.

Not sure you understand the problem. Due to the configuration of the roof, the slope runs PERPINDICULAR to the long dimension of the joist. Therefore, along the entire length of the joist, the deck will only hit one of the oustanding angle legs of the top chord.

Most of the roof does slope parallel with the longspan joists, but at one end where transitions into another element of the building I have this situation.

When things are steep, remember to stay level-headed.

I recommend that you get additiona info. by discussing this with an erector, deck suppier and fabricator.
