2009 IRC - ICF Wall Construction
2009 IRC - ICF Wall Construction
(OP)
Figure R611.9(9) shows a roof truss fastened to the top of an ICF wall. The detail requires tension ties, roof boundary nailing and other stuff well in excess of what they require for a truss on top of a wood framed wall. Why the difference? I called our state code officials and they have no idea why.
FWIW, we are exempt from seismic design for residential structures in NC.
Thanks in advance.

I would not feel comfortable living in a concrete-walled structure in a hurricane region knowing there is not good connx between roof and walls.

So back to my original question, "why would ICF construction be any different?"

Then how do you nail the perimeter of the roof deck?
