SIP roof

[COEngineeer]

So pretty much I have this house that has sloped flat roof that is supported by dropped beams every 5 ft or so. These beams will support SIP going other direction. These dropped beams will cantilever about 5ft for look out.

Here is what I'm worried about. I did specified hurricane ties at the look out for each dropped beams but how about the SIP onto the dropped beam? Is it easy to connect the splines to the dropped beams with simpson hurricane ties? I'm designing it for 90mph category B. I just never specified SIP on my drawings before. I'm not sure how it connects together. If you guys have a good link about SIP roof I will appreciate it.

I haven't worked with SIP panels very much, but I had the same question. All I could ever find is that the SIP screw (long screw)is used for everything, including the uplift. I found one website that had a lot of details.

Go to literature dowloads then SIPs detail book, or what ever else you might be able to find on the website.
I worked with the builder and supplier to about the size of the SIP screws they were using, and worked from that to get my spacing I was happy with, for all the various connections, including roof uplift.

Two manufacturers of SIPs are "Premier" and "Precision"

And they typically use long screws, although it would seem Simpson products could be used, but you should ask the manufacturer.
