Semi-rigid fixation

Some sources have suggestions regarding the determination that the system works semi-rigidly. With this proposal, they generally refer to the ratios of the Diaphragm Floor displacement to the Diaphragmless Column (without floor = no diaphragm) displacement under the same horizontal force. My question is: a) How can I see the displacement of each column without diaphragm in İdecad? b) and how can I give these columns the shear forces in the diaphragm system? c) Where can I see the floor displacements only as displacements, except for Irregularities etc. d) Do you have any suggestions for semi-rigid fixation?

DEAR AUTHORITIES OF IDECAD, I would appreciate if you could answer the following points without reference to other addresses (previous threads) in the Forum. Some sources have suggestions regarding the determination of the semi-rigid operation of the system. With this suggestion, in summary, Diaphragm Floor They refer to the ratios of the displacement of the Column without Diaphragm (without floor = without diaphragm) under the same horizontal force. My question is: a) How can I see the displacement of each column without diaphragm in Idecad? b) And how can I give these columns the shear forces in the diaphragm system? c) Floor displacements, Irregularities etc. d) Do you have any suggestions for semi-rigid detection?

Hello, a) In order to solve a structure whose elements are attached to the slab without a rigid diaphragm, you need to activate the "creating rigid diaphragm" option in the slab settings. then 3D frame In the image you can see the rigid diaphragm itself and which nodes are connected to the rigid diaphragm. In the report, on an element basis, if the element is not connected to the rigid diaphragm, it is written as "the element not connected to the rigid diaphragm". In the attached sample picture, the floor there is considered as a rigid diaphragm. The slabs on the edge are solved with the rigid diaphragmless option. b) You can give an external load to the nodal points of the columns.

c) The displacements of the elements are not printed in the report but are given for any download in the deformation section of the 3D frame view. d) Attached link may help you.
