@Claudio Pedrazzi #Claudio Pedrazzi Thank you for your valuable reply sir, if I get different modes with respective different frequencies, does the frequency that meets the vibrating motor frequency (16 Hz) at the mode of structural collapse or something mean I have to increase the stiffness of the structure, or should change the structure design. Am I correct sir?
