Hello, In your project; -The beams defined by giving + 170 cm level on the ground floor are not connected to the columns and the curtain on the E axis. In case the beams are given a positive level for their connection, an upper level should be given to the columns and the shear to which the beams are attached. The beams, floors, and domes between the EH axes should be placed at a negative level on the 1st floor. -The right end of the curvilinear beam K1 is not connected to the beam K3. Define the beam as two parts as in the example. The D1 slab in this region does not need to be operated as a rigid diaphragm. Check the "creating rigid diaphragm" option from the slab properties. The sample project in which the two situations mentioned above is attached is attached Some other notes: -1 There is no perimeter wall in the basement floor, so it is not considered rigid. it would be appropriate. - Some domes are not connected to the structure at all. (For example, the domes on the EF axis) If the domes are to be solved together with the structure - and it is seen that the support conditions are regulated - its geometry should be formed in such a way that it can be connected to the building elements and a solution should be made according to the semi-rigid diaphragm method. -The supporting conditions of some domes are arranged depending on the beams. (Example the large dome on the 1st floor) However, the edges of the dome hardly connect to the beams. Its geometry must be arranged so that it connects to the beams. Good work"ahmetercolak":1bjoj31a" said:I added the project. I don't understand why I am getting a deflection error because the marked beams are at different elevations. Another issue is how can I fix the system stiffness problem without changing the project too much.
