Hello, I am getting an error that there is an alpha of less than 0.7 on the basement, ground and 1st floors while receiving the report in the project I have uploaded, how can I fix it? Good day...
 
Re: alfai error Also, when I decode the system as a mixed system, I do not get an alphai error, this time I get the warning "the ratio of the total shear forces to the total shear force is less than 0.40".
 
Re: alfai error In your project: * You don't have any curtains in the x direction, but you got the structural system behavior coefficient of 6.xx * 4 of your 6 curtains in the y direction are not continuous in their own axis (y direction). * Columns between 3-16 and 20-33 axles on N axis are not connected. * moreover, the columns in question are not even connected on the floor with rib flooring. * Columns such as S9, S10, S12, S13, S16, S30, S31, S41, S50, S51 etc. are also connected in one direction within the system. * It would be better if the columns on the same axis were arranged in the same direction, staggered. (One x one Y direction) * Increase Concrete Quality. * There are columns that are very delicate. (like 25/30 in the middle of the building) * You have a ribbed floor on the ground floor, but you did not connect the columns even on that floor. * Review loft floor and beam loads. * You can consider HYK. In summary, reconsider the carrier system. Add curtains in the X direction. Increase the column sizes. Solve the semi-rigid diaphragm. N. YILMAZ
