Natural Frequency of a rigid diaphragm floor system

Natural Frequency of a rigid diaphragm floor system

Natural Frequency of a rigid diaphragm floor system

(OP)
I have modeled a balcony floor to be erected inside of a much larger building in Ram SS and also in Ram Advanse (Ram Elements). What is the easiest way to get the natural frequency of the floor system?

It appears that the Eigen Solution is based on a vibration frequency in the plane of the floor. I am looking for the frequency for out-of-plane movement.
