I have a couple questions about metal connectors (e.g. Simpon Strong
Tie connectors) that are used with wooden posts.
First, I often see post bases set in concrete which have two straps
extending upward to connect to opposite sides of a post (e.g.
Simpson's CB series). About what axises, if any, does
such a connection have the ability to resist moment? How about
lateral loads at the base?
Second, I also see caps for a post-beam connection which have a square
plate sitting between the beam and post, with a pair of legs folded up
around the beam and an orthogonal pair of legs folded down around the
post (e.g. Simpson's BC series). These resist lateral forces parallel
to the beam; how about lateral forces perpendicular to the beam? And
what about moments?
Lastly, is it possible to use these or other metal connectors to
design a wooden moment resisting frame?
