If the column and wall share the same plan location (column centroid, wall CL), then they always move together. When there is a step in a roof where one beam is higher and another is lower, supported at the same point, then two stories are always required…

1. A lot of people use no-torsion beams. Program manual section "38.1 Beams" discusses why it's a good idea, especially for beams that are deeper than wide. 2. Beams are all meshed as part of the slab so it does not matter how they are modeled, segmented…

No, I would caution against mixing hanging columns and standard columns in the same column stack. If a beam on say level 2 is hung from a hanger that hangs down from say level 4, then a hanging column should be modeled on level 2 and level 3, and on…

Only model one outer slab edge. Inside this all-encompassing slab edge, model 2 deck areas, one for each slope. Snap the deck areas to the beam line along the ridge (and along the perimeter beams). If you see the deck shooting out into space in 3D, it…

You can do that. I would recommend that you define the initial first story height using the normal floor to floor height. Then model a mat footing or a series on continuous footings under the elevator walls (modeled on the lowest layout type). Then lower…
