Hello, We talked to you on the phone before. I told you that you need to increase the curtain ratio on the first four floors. In the program, the AlfaS control is on the floor above the foundation or one floor of the floor that is considered rigid. However, AlphaS rates for each floor are printed in the Earthquake Regulation General Report. If you want, ignore the warning and refer to the alfas values on the next floor. You can decide. But to solve R=6 hash system; You need to increase the alpha s values I marked by adding curtains to these floors. Since the floor area of the floor is large in these floors, the alpha s values are small. P8 curtain is forced to bend. It requires more reinforcement area in the middle of the column. You should thicken or enlarge the P8 and P10 curtains. Also, even if you increase the concrete class, it can relax without bending."Dira":3iuci612" said:Hi friends, in my project consisting of 2 basements + ground + mezzanine and 17 floors, my 2 curtains on the basement floor give the problem of shear safety + reinforcement insufficient, whatever I did. I increased the size of the beams connected to the curtain in whichever direction there is a problem for shear safety. It still didn't work. I increase the diameter of the reinforcement. The program starts to increase the reinforcement intervals between 3 and 5 cm. I increase the concrete class, it still doesn't work. I increase the size of the curtain again and it didn't work. No matter what I did, I couldn't overcome this curtain problem. I would appreciate it if you could help meYou do not have permission to view link Log in or register now.
