Seismic Response Modification Factor - 2-story wood home w/daylight basement
(OP)
Just out of curiosity, what do most people use for the R-value for the situations where you have (2) stories of wood walls above concrete retaining walls on (3) sides and wood on the front of the daylight basement?






RE: Seismic Response Modification Factor - 2-story wood home w/daylight basement
I'm debating with a friend over this issue and the argument is whether or not to use R=6.5 or R=4.0. Just want an opinion from this forum as there is usually a lot of help here.
Thanks.

Don't penalize the wood. If you really want to, you could do a two stage analysis.

Because of the stiffness difference between the wood and concrete shear walls, I'd be concerned that the basement will tend to act as a three sided system. Consequently, I vote for the use of a conservative R value.
The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

Or CME that is not strongly linked together at the corners with anything but the mortar?
reason I ask is the " full height" of the front wall and the two side walls are actually two stories, right?

I'm torn between 6.5 and 4 at this point.
