Based on the maximum roof displacement and fundamental frequency figures for 'frame + shear wall' modelling, it is observed that the effect of a shear wall opening becomes increasingly important for building structures higher than 15 storeys.
Consequently, the fundamental frequency at 50 Hz and its side bands like 45 and 5 Hz are dominant frequency characteristics for this study as well as second harmonic effect.
For the one-port case with a single-tone excitation at the fundamental frequency, we showed that the equation relating S and Z reduces to the same well-known equation for the linear case if we assume that no energy is transferred to frequency down-conversion.
