Knee Braces
Knee Braces
(OP)
I am planning on using knee braces to resist seismic loads on a deck attached to a single family home. (I can't show that the existing walls are adequate to resist the load, heavy snow loads).
I was discussing this with a colleague and he told me a local building department here in California told him knee braces are not allowed under the new code because there is no R-value listed for knee braces. I was planning on using 1.5 for timber frame.
Has anyone else come across this restriction?

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

woodman88 - I probably should send an email, but I didn't want to raise a question they weren't concerned about.
I discussed using a cantilever column with the client and he doesn't want to use steel, or embed a wood post in concrete.

Rarely a good idea, but maybe okay with an R=1.
