Please see the attached images for my problem. I have defined 6 separate corewall. When I view the results it appears there is an error in the value for the top 'cut' i.e. storey 11, cut 2 that comes out much larger than the lower values.
When I view the results graphically it shows the centre of rigidity for all the cores converging on point 0,0,0.
What could be the cause of this?
It seems there might be some inaccuracies in panels \ stories definition.
I have defined stories from scratch and corrected geometry of panel 168 using addin from http://forums.autodesk.com/t5/Autodesk-Robot-Struc
Still 2 cores ....
