ide performs static flooring analysis separately from the structural system. It already says in the training notes. "Slab analysis is separate in the 3D system". I'm wondering here. While doing the idestatic slab analysis, it does not consider the bending stiffness of the beams, that is, it accepts the beams as support and solves the slab with finite elements. This is how I understood it from the solutions I examined.... however, depending on the span through which the beam passes, the bending stiffness of the beam will change, the beam will deflect, however, the floor will collapse, the internal forces of the floor will change its displacements... I think it would be a more realistic solution if only the columns and curtains were accepted as supports... Also, the forum talks about semi-rigid diaphragm in its 7th version. In this case, it is necessary that the ide static tiles include in-plane deformations in the matrix, so I understand that the tiles are no longer separate from the 3D system, but are included in the system matrix... is it true? good work aet
