Thanks for the video, but you did two mistakes , first you must make mesh for the slabs, If you do not do that , dead and live loads will transfer to the corners of the slab, i.e., directly from slab to columns, no loads will transfer to the beams and beams will carry only their self weight. secondly , diaphragm must define separately for every single slab, for your six story building, you have to define six diaphragms. when you defined all the building as a one diaphragm, you did not permit your structure to sway laterally.
in the FE theory, which structural analysis software based on, the loads and moments are transferring through edge nodes of the element , it you do not mesh the slab, the software will consider slab as one element, so all the loads on it will transfer through its corners which will transfer directly to the columns, If you mesh it, more than one nodes will be located on the beam so the loads will transfer firstly to the beam then from beam to column, which is more real the way you did is not wrong but its not represent the actual behaviour of the structure @@KSSE_Engineer
about the diagram, old version need to do like you advised, but new version no need, just like Etabs, can define one diagram assigned to whole structure then software will automatically generate different diagrams for each floor
Good attempt and informative tutorial .....thanks sir
Most welcome
Sir are you not considering Load Combinations?
Do we have to mesh the slab?
You can , if you forgot the program will use a default mesh.
@@KSSE_Engineer it will be as the slab size

I think it’s not wrong or mistakes. You can do the way you said that’s also correct. In order to make sure it’s correct do a verification.

where is the next videos ? or the playlist?
The video is included in the SAP2000 playlist. Plz check it.
