Design of RC Cores
Design of RC Cores
(OP)
What is everyone's approach to RC cores. I normally build up the core in RAPT and design for Axial Load and Bending. I change the tension controlled and compression controlled reduction factors down to 0.4 and 0.3 except when I provide compression ties to the vertical reo, then I keep the factors at 0.8 and 0.6.

The reason I ask is that I see people ripping wall forces out of etabs and assess each panel one by one. I have no issue with doing that I'm just a little concerned by the coarseness of the FE meshing. You pull forces out but don't get the smoothed design stress interaction. Like with a ram concept floor model, you don't design for the peak spike in slab moment over a column but distribute it over some slab strip width.

What you're getting at is people should be using an M / Z approach for the whole core as opposed to isolating each panel?

It would be the Column module that produces M/P interaction diagrams.

Obviously this relates to RC in-situ cores, I can foresee some issues arise when you start using precast panels stitched together as cores.
