Hi there,
I was just wondering what the best way would be to model an upstand beam in RAM Concept?
In this scenario, the upstand beam is an edge beam spanning between two stiff core walls, and forms one of the edges of a 2-way slab.
Understand from the Help Guidance that the upstands should be modelled as "beam" elements, but what is the best way to simulate fixity (into the core wall) at the top of the upstand? Should we locally model walls above, and if so, will this skew the bending moment plots in the slab/beam elements - particularly to the intersecting beam running parallel to the wall?
Or, is it appropriate to model a pin support at the top of the upstand in line with the centre line of the wall? The main concern here is that the fixity at the ends of upstands are not accurately represented, and the subsequently large deflection outputs.
Any advice would be greatly appreciated.
Many thanks,
Vida
If you model the upturned beam normally, but also model the walls above using upturned beams (even deeper ones), then I think you'll get what you want. The behavior of walls above the slab and upturned beams is very similar.

Thanks Seth, appreciate the response.
