hello. friends, in my project, I have a cutting safety problem in the elevator curtain. I am using ide 8.61 in the basement floor, I could not solve how much I increased the size of the curtain.
 
Hello, In your project, elevator curtains do not recover from the 0.22Achfcd condition. It seems difficult to recover by increasing the thickness of the existing curtain. By adding shear curtains to the appropriate places in your project, you can save them by reducing the shearing forces. Although you have chosen a mixed system, your AlphaS ratio is in the Y direction of 0.27. If you want to solve a mixed system, you should add curtains in Y direction. In other case, you need to solve for high ductility. Also, you got R=6.99. You should choose this R coefficient according to the table below. The value you get now does not comply with the regulations. Also, you used 5% calculation and section tolerance. I recommend not to use it. You are using version 8.61, I suggest you to update to version 8.62.
 
hello sir, first of all thank you for your reply. I solved the system with high ductility, but this time I have a cross-sectional problem in my curtains in the basement floor, I added curtains to the system, I could not fix the error in different positions, and you also said 5% calculation and cross-section tolerance, where can I change this value and how much do you think I should get. Thank you very much in advance

Due to the situation you specified, you need to change your design, add curtains and increase the dimensions. You can change the tolerance values in Analysis Settings -> Load-Security section. Calculation reinforcement and section control tolerance is at the discretion of the engineer.The analysis results are tolerated at the rate entered here.To be on the safe side, take this value as 0
