I have a building that is mostly two stories with a connected one story area; the two areas are structurally connected so it is preferred that they are modeled together.The one story area has a sloped roof. When I try to slope the roof of the one story area, the slab of the two story area stays connected to it causing the beams and diaphragm of the one story area to slope upwards (see image below). There are two different decks assigned to the two different areas already and there is a slab edge between the different decks. Is there anyway I can properly model this, or do I have to leave the roof slope out of the model?
The slope of the beams follow the elevation of the columns (and walls), and the slope of the deck follows the beams.
If the beams and columns within an area of deck (deck polygon) are not in a single plane after elevations are modeled, then the deck will diverge from the framing to maintain a single plane.
If there is ever a column supporting beams at two different elevations, then those two beams have to be on separate levels types with the higher of the to beams on the higher story. Where you have a small step but where the deck is supported by the same beam on both sides it's best to model a single flat level and ignore the step in my opinion.
