For a flat roof that lays in the XZ plane: I would normally assign one of the nodes in the center of the roof as the master and slave all of the other roof nodes in the XZ direction.
Would this methodology still be applicable for a pitched gable roof (slope = 5 degrees)? It does not seem correct to only assign one master node and slave all of the other roof nodes when the roof is not flat. It also does not seem correct to use the XZ slave direction because the roof is sloped so it is technically not in the global XZ plane.
How can I properly model the roof diaphragm for a pitched gable roof? Should I have two master nodes, one for each side of the gable roof? Would I still use the XZ slave direction?
Any insight that can be offered would be greatly appreciated!!
