Masonry SW and Steel in wood construction

Masonry SW and Steel in wood construction

(OP)
Hi I was wondering if there are any good references on combining masonry shear walls and/or steel moment frames with wood 1-3 story wood structures that utilize wood shearwalls for the majority of the LFRS. Does the R value change for the wood shearwall design if only one masonry wall or one moment frame bay is used as well. Thanks

RE: Masonry SW and Steel in wood construction

When we design residential structures (under the CBC) that are mixed, we use the lowest R value (typically the one for the steel or masonry) for all walls in that direction.  

So - for example - a wood shearwall that is acting in the same plane as a steel moment frame would be designed with the R of 4.5, rather than the 5.5 that is typically used.
