The building code requires structural framing lumber to be marked by an approved agency although they don't require that for ohia posts since generally it gets approved by a licensed engineer or architect.
Ohia is a very hard brittle wood, I don't think I'd care to use it for joists or other areas requiring tensile strength. It does have very good compaction strength which is why it gets used for posts so frequently.
It makes a nice flooring lumber and is great for fine furniture. Wasn't it also used as railroad ties when we had a rail system?
