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?
