The room is about 10 wide and 16 long. Basically its a diningroom that cantilevers approx 8 past a solid wood beam. Restrained support and cantilever the negative moment shall be determined according to the floor continuity scheme taking into account all variable and permanent loads acting on the floor after hardening of the composite connection and long term effects. A day until they re level.

The main floor will also have a little normal slope due to deflection so you want the cantilever really really stiff so you don t notice any change in slope where they meet. The cause of these may be the same or may be different. Tack a beam under the sagging joists. The hump is where the down sloping cantilever meets the main floor.
