Built-Up Wood Posts

[RachelP]

I have an existing post that is failing. I would like to "beef up" the post by adding 2x lumber on two sides of the post. Has anyone done this before? Would you analyze it like a built-up column and use section 15.3 of the NDS?

Probably. It kinda depends on the nature of the existing failure and whether not you intend to releave the post of its existing load prior to reinforcing. What say you? If the original post works in parallel to grain compression without crushing, my preference is to approach the design by simply increasing the moments of inertia but no other parameters. That way, your contractor won't have to relieve the existing load on the post which in a boon to the project.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
