I am constructing first floor over existing 15 year old load bearing brick masonry. there is one back side existing wall 9'' thick & 7.71 m long,which has two window grill opening at one side of wall.These openings top is 12 cm below RCC slab  bottom,with a 12 cm thick RCC lintel between them. these opening forms two brick masonary column of 0.22 x 0.22 x1.38 m size.
I have to construct a new 4'' brick wall of 3.10 m height over this backwall.Two RCC inverted beams of size 0.22x0.22 m & 1.5 m span,supporting 9'' thick new wall,rests on this wall at one end.This beams are constructed on top of the old roof slab.
Can this wall take up a load of 4'' wall & two concentrated loads?
The total UDL of 15 KN/M (weight of 4'' wall 7.5KN + GF slab load 7.5KN)& two concentrated load of 23KN & 25 KN  acts on the top of this wall.
what would be the stresses in the two brick columns? Can closing one of the opening with brick masonary will be sufficient to relive stresses in the columns?What care should i take while closing this opening with brick?
it will be very kind if hon. ER.Rangarajan answer this query.
