My basement window is sitting on 10" concrete block. On top of the wind is a 2by treated sill plate. On top of the sill plate are 2 floor joists and there is some slight deflection in the sill plate. The joists are cantilevered to the deck. However there is nothing but the sill plate holding up the joists. The exterior cantilevered deck joists appears that they may be sitting on steel angle but its just the angle that is used to support the brick facade, I dont believe it is there to bare load. Its not a lintil that would also support the sill plate. I had a structural engineer in to look at it, in addition to other issues and he suggested bolting steel angle to the block. I did some quick reading and to get any type of support from that proposed solution, the angle would need to be rather large and make the window in operable. Any ideas?
