Hello, I get the error "There is an alpha less than 0.7 on any of the floors" in the structure attached to the message. How can I solve the problem. I wish everyone a good work.

Re: alfai Select the ductility level as normal according to the R coefficient of 5, the problem disappears.

Re: alfai Hello; Your project is included in the 'system in which all the earthquake effects are carried with frames' in terms of the Earthquake Code as a carrier system and is included in Table 2.5 - 3.1 since you do not use any cross members. R=5 and ductility level you need to do the normal solution. However, you preferred the solution with R=5 but high ductility level. That's why you're getting an error. You can detect this error if you examine the Selection of the R coefficient page in the optional report. Apply the ductility level normal selection from the analysis settings for both X and Y directions. Good work.
