effect of new oppenings on existing wall + slab
(OP)
Making new oppenings in existing masonry. Above is RC wall/parapet and a slab.
Do making new oppenings affect parapet (200/1500 mm) in any way?
Because of new oppenings I think that horiz. forces (wind) on the parapet affects existing slab, but not a parapet. Parapet is a cantilever and bending moments at the base of parapet transfer to a slab since parapet is fixed into the slab right?
What Id like to know is does existing design conditions of parapet change because of new openings below a parapet?
Im afraid that becuase of that there may be a need for additional reinforcement (anchors from parapet to a slab).
When it comes to verical loading, parapet now acts as a deep beam, so I dont think there will be a problem since it is 1,5 m high.

So anchoring reinforcement parapet - slab is not affected by making new oppenings at all ?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

But do those new wall openings significantly decrease any lateral shear wall behavior of the walls themselves?
