Is an upset and a upturned beam the same thing?

Sounds like a pretty common situation when using HCF. You often use box section beams with wide bottom flanges on which you place the HCF or other such variants - when you need a taller beam and have to protrude the least problematic direction for the beams to grow in is almost always downwards as a smaller protrusion there might be dealt with locally within the technical space below the slab without lowering the ceiling below that or just lowering it locally rather than loosing floor-to-ceiling height at the entire floor of the building.

We don't have seismic here though - no idea whether such solutions are practical or even viable when seismic performance is needed.
