Load transfering to Shear-walls

[Stilie87]

Hi!

I have a multistory building which is for some reason getting unreasonably large forces on som shear walls. 

For Wind-cases in Y-direction, one shear-wall which is oriented in X-direction is getting large shear-forces. The walls are free and is not supposed to work toghether. Is there a way to avoid this effect?

You want Axis B core wall to work for loads on X direction only and the the one on axis C only to work for loads on Y direction ??

What do you mean by "The walls are free" . Is the structure separated ( 2 pieces)?

The walls have linear-releases, and should not transfer moment or shear to each other. 

It seems to me that panel number 29 has to large horizontal shear-forces. If you compare it to panel number 32 and 37.  This seems a bit strange to me since the force is placed in Y-direction.

Could you share your model?

Nothing strange in the results.

The wind in the Y direction is applied to the center of garvite which is at x = 13.42m, the center of rigidity is at x=26.3m. The twist couple created is taken up by the shear walls in X direction.
