This is in reference to problem #15 from Hiner Seismic Review. There is a horizontal roof diaphragm made out wood structural panels (WSP) with 15/32" rated sheathing. I have never taken a wood design class, so this may be a very dumb question. But I can't figure out how they said it was CASE 3 for IBC 2305.2.3?????
I don't know how to tell by looking at the diagram whether it is blocked or unblocked? also is the spacing of the nails given? Is it that when there is roof wooden truss supporting the horizontal diphragm like in this case, you don't require blocking? what is blocking in this context anyway?
PLease see attached.
ANy help is greatly appreciated. THank you!
