Band Beams/Drop Panels in Ramped Slabs

[crax]

Evening all,

I've got a question about band beams and drop panels in slabs that are graded to suit a trafficable basement.

If my slabs are ramped to say 1 to 16 per the traffic engineer's requirements, and I have band beams in the slab, is there any functional difference than if the slab was say 1:50 or 1:100?

Based on the geometry it doesn't seem feasible to have a flat soffit to the band beam, but I'm hoping to get some insight whether ramping the band beam to the same grade as the slab is common practice.

Similarly, with the drop panels it seems possible to have flat soffits, but again it's the same question whether the ramped slab over changes any of the calcs or fundamental principles.

Thanks in advance

Not sure if I am allowed to bump a post, but hoping anyone who has designed any multi storey residential structures could weigh in here! Thanks in advance.

You can bump it as often as you wish. Offhand, I can see no functional difference in the 1/16 slope.
