Karamba Wall and Slab Fixity Issue

Grasshopper Karamba3D
1

Hello

I am trying to model a structural system that uses the walls and floors to work in unison. A performed a simple test of how karamba would model this and I got the following result below. I have four supports at the outermost bottom points of the the walls with pin supports in all three directions. There are no other supports in the model. However, the walls do not translate/deform with the slab as expected. I would be expecting to see a perfect (visually at least) hanging wire kind of shape, but the walls corners do not translate. Is there an obvious mistake with fixities that I’m missing? Code attached. Thank you!

Hello @Colton,
the walls are very stiff with respect to in-plane deformation. The upper and lower floors prohibit a rotation of the walls about the y-axis. So mostly in-plane Z-displacements occur.
You can visualize the inplane-deformation of the walls by setting the deformation scale to a large number.

P.S.: In order to get more colourful results disable the display of the middle plane of the shell elements by unhooking “Element axes” in ModelView/Annotations.

This makes total sense. Thank you @cp1
