Abstract
A crowd of people can generate large loads and this may be a concern for both safety and serviceability evaluation. For design it is important to identify an appropriate load scenario. If a person keeps jumping, the resulting dynamic load will be cyclic. Hence in certain situations it can generate a resonant response of a loaded structure. It is instructive to provide a mathematical model to evaluate the load producted by one person jumping rythmically.In this context, the peak load can be also 5-7 times the person’s weight. A coordinated jumping load can induce a resonant response in a structure. If the frequency of the dynamic load induces a resonant response in a structure, a resonant situation can arise. The response of the structure can be amplified greatly. In this research mathematical models are proposed to represent load generated by one person doing single jump and jumping rythmically. It is proposed a comparison between the results, obtained by mathematical models, and measured load.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
