securing jack post to concrete floor.

I'm putting a jack post to support a beam in an addition per the approved plan, there is a footing already under the concrete floor for it, and i'm using lag bolts to secure the top to the beam. to secure the bottom plate to the floor do I need to use a sleeve anchor? can I get away with masonry nails? is there another option I'm missing? thx!

Your building inspector could answer that. They want anchors in everything now days. Use to be you could run a bead of construction adhesive and shoot some masonry nails to hold walls.

Since you have an approved plan, there should be a note on the plan describing the required method of attachment of the jack to the floor. If there is no description, call the designer or the building inspector. Typically for a retrofit, the designer will want either epoxied in place bolts, sleeve anchors, or an expansion anchor, but they might accept a Ramset type anchor. Doubt that masonry nails would be acceptable.
