Slab Spanning Direction Issue

[eoin.duggan]

Hello,

I'm having an issue with defining the slab span direction in my building model.

I have composite floors and metal deck roofs that I wish to span in the X-direction. However, they currently span in the Y-direction, despite having specified that the panels are to span in the X direction.

On the attached model you can see that under gk_upper roof that not distributing any load to the beams running the Y-axis. I would appreciate your help in rectifying this.

Thanks,

Eoin

Eoin,

You need to change the local panel orientation to match the global X asix orientation,

To do this, I had to change your structure type to shell design - then select your roof panel and go to geometry - properties local panel direction and change to global X vector

(see load distribution of roof panel below)
