high frequency problem

[civilman]

In the attached project, the frequency was 0.8 in full-rigidity, and only one slab was giving continuous error. When we increased the number of modes, the frequency increased to 2 values. I want to know the errors in my data entry or analysis settings.

the attached project turned out to be like 0.8 in full-rigid frequency, and only one slab was giving continuous error. I changed it to semi-rigid because the rib should be semi-rigid, but I encountered the problem of insufficient mode. I want to learn about the errors in my data entry or analysis settings.

Hello, -The construction period is around 2 seconds due to the faulty formation of the rib beam rigid arm of the D52 slab.The typical rib starting tooth width of the D52 slab and its continuous slabs is set to 25 cm on all floors. In the -8 version, the rigid arms are formed correctly as you add the project in the semi-rigid solution.
