Strange results in core walls (tension vs compression)

[Jummybear]

Hi all,

I am trying to analyse my core walls made from blocks and put some reinforcement in it. I met some strange results in some corners. I assume to have some tension force due to wind load. And I have it, but! Tensions force in upper wall roughly changes to compression in bottom wall... That looks strange for me, I asuume smooth tension force/stress along wall edge. As usually, the reason could be very simple but I cant figure it out... Asking for help. 

PS There are walls #315 and 313 on my pictures, combination case number 62 (ULS_16...). Model without results is attached.

another problem: after splitting panel to separate ones I cant get reduced results for panels for some panels... Redifined stories, but this doesnt help... File attached.

PS For example panel 136 - results NA

It looks like second issue is solved. I remeshed all panels from the begining, some of them were deleted and modeled again. Tension/Compression results still under investigation.

I think the problem is the shear linear releases along the verical edges that you assigned for these walls . Even for load 1 , Self weight ,these walls have tension.

I don´t know which were your reasons to set these releases ,but as it is now the perpendicular walls are acting independtly from each other.

If you delete the releases for all the walls ,then , results look way better !! See results for vertical force on the whole wall in your original model compared to the model with no linear release on the walls

In this projekt I work with 2 Robot files synchronously all the time. One with "rigid" connection between 2 walls and wall-column, another with released connection at the same place. The reason is very simple: from first model I get shear forces/stresses in vertical joints, from second one I get max tension/compression forces/stresses for pile raft and walls.
