Simulating Crowd Vibration with Traffic Load

Streamlined sections in suspended structures can create dynamic responses that are particularly impactful. One notable source of noise and vibration is the weight of human footfall, which can be a nuisance for those using the facility. The objective is to ensure that the structure can withstand the stresses caused by the occupants. The approaches can be the following methods: (i) an analytical approach, which involves calculating the structure’s performance during the design phase, and (ii) an experimental approach, which entails measuring the vibrations of the structure during use. This study proposes an experimental modal analysis procedure for evaluating the vibration functionality of an existing structure under the influence of excitation caused by human activity.
