high displacements when a series of triangular cladding is modelled

[ssabDJVSQ]

As per the suggestion by the forum, I've modelled a series of triangular claddings to obtain a flat cladding, and the load distribution is happening as intended. But I see that the displacements are very high in this case, how to solve this?

hi @ssabDJVSQ 

it's hard to say without having the model. zip up your model and share it.

hi @ssabDJVSQ 

the cladding provides no horizontal stability, the movement is due to the lack of symmetry in your framework. If you wish to utilize the diaphragm action in the walls, you must model them as panels.

In my model, the lateral stability is provided by the frames in one direction and bracings in the other direction. I use cladding only for the load distribution. In that case, why do that high displacement happen? Is there any other method of modelling?

hi @ssabDJVSQ 

just to make sure of this you can briefly create a plan model with your gantry and uniform loads.

I am not sure that hight displacements are due to cladding triangular shape, but instead to the frame shape. In this example you'll see that the displacement is almost double that of a classic portal frame.
