Ridge beam support.
Typically a BD is going to go over blueprints in a plan review and they're going to be looking for blueprints prepared by a licensed engineer who will place a raised embossed seal on the original prints you are turning in with your permit application. I'm guessing you're not a licensed engineer, and most of us here are not either, and even if one of us was that person might not have enough information to answer the question...
When I hear ridge beam I think of the board at the peak of a roof... That doesn't sound like what you're talking about, is this just a beam under floor or ceiling joists and what is it supporting? If you're talking about it being inside a wall, why not just make a load bearing wall?
