The resonant frequency is the frequency at which any excitation produces an exaggerated response. This is important to know since excitation close to a structure's resonant frequency will often produce adverse effects. These generally involve excessive vibration leading to potential fatigue failures, damage to the more delicate parts of the structure or, in extreme cases, complete structural failure.
