more than one rigid diaphragm was detected in the project, when the warning is received, it is understood where to look in the program to find out which flooring the problem is, when I look at the forum, my friends immediately find where the problem is, I wonder where they are looking. Thanks in advance for your answers[/ quote] Hello, First of all, the message "more than one rigid diaphragm detected" is not a problem, it is a condition. You should know whether there should be more than one rigid diaphragm according to the slab continuity. If not, you should arrange the data feedback according to the situation where it should not be. The rigid diaphragms in the structure are 3D frame you can see in mode.
