Resonance curve - the case of pedestrian laoding on structures
Resonance is one of fundamental concepts in structural dynamics. In simple terms, it occurs if a periodic force is applied to the (structural) system at or near one of its natural frequencies. This leads to the amplification of the response relative to the case when no resonance occurs. The consequences of this phenomenon can be severe, from accelerated degradation of the structure, lack of fitness for its purpose, to the catastrophic failure. Therefore, understanding this phenomenon is of critical importance to any engineer.
