Suspension Coefficient <0.60 Error

[ctolga]

Hello; In the project, the height of the ground floor will be 5.5 m. Here, the beams will be turned at 3 meters and a floor mezzanine will be built without flooring (it is said that we will do the flooring later if necessary). When I analyze, 3 rigid diaphragms are detected. I get error ni<0,60 as a result of the analysis. What should I do to resolve this error. When I want to solve the stairs together with the carrier system, it is recommended to do it with the response spectrum method. Is there any harm in solving it with the response spectrum instead of mode combining? Do you have any suggestions and places that you see a general deficiency in the system? Project Link:

you are counting on that floor, but it may or may not be, I think you should decide on this flooring event in order to solve this problem.Response spectrum calculates the internal forces of the elements and gives more realistic results, you don't mind. In some beams, there is both a live load and a wall load, and more than that, evaluate whether this actually exists. respects
