brabus upstand beam application is same as downstand just that in this case you can’t cast the slab and you will assume you are coming back to cast the remaining top beam.
Application
There are at times a slab may be failing in deflection due to span and you are lucky there is a wall along that line u can break such slab using upstand.
Reinforcements arrangement may change .
Good for roof slab edge also like a parapet
Disadvantage
It limit renovation works for partitions due to the drop which will reduce flow of movement
The only zone attention is needed is when changing a continuous beam from downstand to upstand stress will be generate at that zone and needs to be taken care of with how we crank bar at that area. We have two types of detailing for this one is correct while the most common is not because that zone is not cater for
There’s nothing like hidden beam structurally though but the application seams common here maybe when Nigeria as it own code more research and adoption may follow.
