Log Home Seismic R Value
Log Home Seismic R Value
(OP)
Currently designing a log structure that is a real menagerie. Uses an Insulated foam sandwich panel roof with log and stud walls, TJI floor joists, glulamms, parallams, and an ICF foundation - a real hybrid. That said...
I saw the post by RockEngineer in 2006, but has anyone come across any more recent guidance than the 2006 article in Structure Magazine on the appropriate R value to use for log homes?
I heard a rumor that there was some new design guidance out there for log structures.

RE: Log Home Seismic R Value
If I would have suggested a person to ask it would have been you. I am always amazed at your breadth of knowledge.

To me, the more important question is what is the lateral load path? I don't see a natural lload path for the lateral loads in a log style home. Though I know very little about them.

Thanks all for checking, and the complement Rock.

I did find out that unlike ASCE 7-05 or the IBC 2006, the IBC 2009 edition refers to a new publication, ICC 400-2007, that is available on the ANSI website below for $25.00.
I have not seen it yet, but understand that it probably does not address the R value issue. Apparently, it deals with Log Structure design and construction "guidelines", whatever those are.

If you follow the above link, it will take you to a page that shows the structural requirements from ICC400-07.
At the bottom of the site, it does adress R and indicates that a value of 4 is reasonable.

I have ICC400-07, and it does not seem to provide this value.
