Uplift Wind Loading Values [RE-wrenches]

[keith]

Hey Graham

The distance is 4' on center. I am definitely vexed on this attachment.
To ad to the dilemma, one section of the building has a spline 1'x1'
ceiling, making it impossible to sell a larger system without surgery to
the ceiling.

Keith,

I am wondering what the distance is between the steel perlins?  I
believe the perlins would prove to be the most secure attachment points.
I definitely would not advise Tek screws and Jeff's battle ship approach
sounds wise.  The simplest and easiest approach may be some type of
toggle bolt if perlin attachment is not workable, my concern with this
method would be measurable deflection, bending or otherwise compromising
the integrity of the overall roofing system.

Graham
