Rigid floor acceptance compliance parameters

[prol0gic]

good work, in the attached picture I am preparing (C-Z2 Qem=10t/m2-1.degree earthquake zone-B+Z+1) in my project, there are panels along the basement floor height, but they do not surround the entire mass, in this case; 1) Would it be a correct approach to analyze the relevant floor as rigid floor (rigid floor number: -1 and R=8)? Should perimeter panels be turned in rigid floor acceptance? 2) Do I need to analyze by taking RIGID FLOOR NO:-2 and R=8 and selecting the option of curtains that do not continue on all floors in the basement floor panels? 3) Or again, should I analyze rigid floor=-2 bus time R=7 and its panels will be included in the alphas calculation and B1 irregularity section calculation (without marking the panel that does not continue on all floors in the basement), what should I pay attention to in this regard, 4) What should I pay attention to in this regard, 4) Doing analysis means that I do not surround the sections with walls on the upper floors with panels in the basement that are not included in the B1 section calculation, will I cause B1 IRREGULARITY? And sure, I did a lot of research, but the information is very superficial and there are not enough resources. I felt the need to ask about the points I got stuck on. I would appreciate if our experienced friends could help me. When I do it, is it enough to only tighten the columns (transverse reinforcements) along the floor to prevent the formation of short columns? (band windows h: 60 cm) Thank you very much in advance.
