Lateral stability for steel framing

[DCStructures]

I'm working on a small renovation. Adding a couple steel beams supported on new steel columns which will be (located at perimeter of room) to replace existing posts (located in middle of room) and create open space in basement.

I need to provide some lateral stability to this new framing and I'm thinking about connecting back to existing basement masonry wall (or walls?) for support.

Any pitfalls/negatives against this idea? Any tips on best way to make this connection?

Alternatively I could use beam-column moment connection or fixed connection at column base, but I'd prefer not to do either of these due ease of construction, more expensive connections, etc.

Assuming that the floor diaphragm and the walls provided the lateral support for the central column, if so, use it for the new ones.
