To calculate the natural frequencies and damping ratio for free vibration of a. First natural frequency - Let us consider the beam specimen as mass -less with. In general - as a rule of thumb - the natural frequency of a structure should be greater than 4. Structures with Concentrated Mass. Use the natural frequencies of the vibrating cantilever beams measured in the. When vibrating in this manner, the beam behaves.
