There are too many joint area problems, I think we need to make a wider change, I think, I increase the curtain ratio, I turn a beam into a curtain on all floors, I increase some columns as the architecture allows (rather than reducing the problem, it caused extra problems on the raft) I tried these possibilities, but it did not work. I am waiting for suggestions from you. Thank you
 
Hello, You need to increase the beam and column dimensions. For a 7-storey building, 40x30 beam size as a hollow block may not save from shear safety. Also, I am sharing the attached document about beam-column shear safety. It will be helpful.
 
I've been reading articles on how to choose the R coefficient, but can I get specific advice for this project? Is normal ductile r=4 appropriate?

You can check the " section.
 
I recommend that you overhaul your carrier system. I have sent a picture attached. You can remove the columns and beams marked with a blue X in the picture I sent, and add the beams I marked with red. You are having a problem with the framework. Some of your columns seem to be connected in one direction. ( Columns S2, 15, 16, 21, 25, 26, 31, 33, 35, 36) Connect them in two directions. When arranging the columns on an axis, you should stagger. When you do this, you will find that many problems are solved. For example, all the columns on the bottom 14 axis are lined up in the same direction. Again, the columns on the A axis and L axis are like this. There is no load (fixed and moving) on any beam. K82 is a meaningless beam. Some floors have connection problems. Change the beams K117-118 with the beam/foundation direction command make it continuous. Enter S19 and S24 columns into the system as curtains. Berat Bey has already mentioned the beam heights. As I always say, while you can pass beams wherever you want when making ribbed flooring, I don't understand how to avoid putting beams in terms of joining the frames correctly, especially when each rib is in a beam position. I also think that the curtain on the far right in the 2nd and 3rd basement floors has no relation with the building. It can also be a retaining wall. So I think it would be better if you didn't add it to the system.
 
thank you nyılmaz sir, would it be more correct or logical to solve this system as normal ductile or mixed? The alpha s value is sufficient, I reviewed your frame proposal, I don't make the final decision, your suggestion made sense, but some are afraid of the stud beam like a bogeyman, is it reasonable to switch to a normal ductile design just to get rid of the bbg?
