Abstract

Prediction of dynamic loads (i.e. ground reaction forces) induced by active groups and crowds of people is one of the biggest challenges in vibration serviceability assessment of structures such as sport stadia, floors, grandstands and spectator galleries. The lack of understanding of dynamic loads due to multiple active people not only leads to economic costs and unnecessary carbon emission of civil structures but also results in safety concerns related to crowd panic due to unexpected and unfamiliar structural motion induced by active occupants. The aim of this presentation is to introduce ongoing research designed to provide a method to reproduce ground reaction forces from multiple active people using wireless inertial sensors.
