Hello friends, After upgrading to the new version, I could not overcome the failure of cutting capacity on some curtain walls. If you could help with this situation, I would greatly appreciate it.

Hello, If you use 14'' reinforcement for curtain stirrups in the selection of curtain reinforcement, the shear capacity insufficiency due to the lack of stirrups will not occur. Before analysis, you must uncheck DS for the same shear walls in the shear concrete dialog.
 
Hello. In addition, divide the beam at the curtain joint points so that the beam B029 can be supported on the curtain on the ground floor. The connection between the beam and the curtain is thus incorrect. You have correctly defined the upper floors.
 
Thanks a lot guys for your comments. But I have solved the problem with the curtain of 14 pieces stirrups. Isn't 14 reinforcements too much for stirrups for application? I also get a warning of insufficient reinforcement area on raft basis. I shorten the distance between the reinforcements and use 18 (although I removed the DS before the analysis), the program does not design as I specified. Is there something wrong that I'm not aware of? I would be very happy if you could help me with this. Good work.
 
Hello, You gave jeans to the curtains for the elevator pit. But you did not define the basis here. In this case, a support problem occurred in the superstructure interactive solution. Set the elevator curtain elevations to 0 and analyze again. The horizontal reinforcement on the curtains decreases to Ø12. Basically, there is no additional problem. You can optimize the basic main reinforcements can be reduced. Information about the elevator shaft drawing is available at this link

2. As a solution suggestion, you can draw a small raft for the elevator shaft under the curtains you have given elevation and adjust the elevations. The elevator shaft foundation can also be formed in this way.
