In this paper, the analytical expressions of the dynamic compliances of both undamped and damped cantilever beams are found by the transfer funtion method. From these solutions, the phenomenon of “pseudo-resonance” of beams is discovered and defined. The characteristics of resonance and anti-resonance are investigated in detail. The resonance frequencies, anti-resonance frequencies and pseudo-resonance frequencies of the cantilever steel beam are also measured. The calculated results of these resonance characteristics are compared with the experimental ones.
