Re: WOOD - Load bearing studs in a party wall

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Well, that's WAY too conservative. The plate height is 8'-1" yielding a l/d
ratio of
64.8. I also won't get many "brownie points" by telling my client he can't
have his
party wall. Yes, the reason for the staggered studs is for sound. Even
though the
resilient channels yields a satisfactory STC rating, it really isn't that
great. The client
wants better performance. Need to do better.

Thanks anyway,
Bill Allen
