16" center floor joists


Anyone know right off hand what would be the ? for Herringbone Strut?

Length = ?
Angle Deg = ?

How often should I have a Herringbone Strut over a 16' Span?

Just curious....

Anyone know if there is any structural advantage to using Xbracing verse solid blocking..... (I've seen solid called out in Cali.... don't think I've ever seen X called out (just blocking) (except on TJ's maybe)

:huh::huh:

Around New England it is called cross bridging. It does not have to be exact length to work, it only looks neater. Some joist spaces may vary a little so we used to make it flush at the top with all landing about 1/4" above the bottom of the joists. Cross bridging works under compression from top of one joist to the bottom of the two adjacent joists. Nailing the ends tight is more important than being the exact length. Solid bridging or blocking prevent the rectangle space between joists from becoming a parallelogram thus spreading the load over several adjacent joists. They should all be cut individually so they are tight but not tight enough to push the joists apart. They should be center of any span over 10' and divided in thirds over 16'. But check your codes because some spans under 16' may call for two rows.
