(OP)
thread507-239063: Wind uplift on roof deck

Hi,

This could be a continuation of the thread referenced above. I am wondering how the OP managed his design? I am in a similar situation, where I need to come u with a solution of securing roof avers and wooden panels resulting from wind roof uplift forces up to -70psf. This is creating an issue as the specified pavers and panels are only 25psf. I am aware that the ASCE-7-02 loading case 0.6D+W (ASD) needs to be satisfied. Obviously, relying on selfweight alone will not be sufficient to satisfy this loadcase. I am also aware there are proprietary systems such as Hanover Ventlock or Guardian, but these are pricey and so I would like to see whether a feasible alternative is possible. This structure is subject to provisions of 2008 NYC Building Code.

Any ideas will be much appreciated.

Are you sure about the 70 psf? That sounds like a Florida level hurricane load.
If you're sure about the wind loads, you might need to go the Miami-Dade Product Search website for ideas.

70psf in NYC must be the corner zones?

They need to be anchored down to the roof slab with anchors that get integrated into the waterproofing. This comes up a lot in nyc and someone will try to tell you something of the sort 'the paver was tested to 120mph' which doesn't help you or mean anything.
