Kurzbeschreibung (Abstract)

In recent years, research on human-induced vibrations has developed several advanced modelling approaches aimed at achieving a more accurate description of human-structure interaction (HSI). The prevailing method involves using the load function from walking individuals on rigid ground as a starting point, considering the deviation when walking on vibrating structures, and incorporating the person as a single degree of freedom (SDOF) model coupled with the structure. However, this approach suffers from the need for case-by-case consideration, as the load model parameters are not universally applicable for each HSI model. To overcome these limitations, this study presents a modelling approach that strives to capture the HSI by accounting for the gait cycle dependency of the SDOF parameters. To apply the proposed model, measurement data collected on an experimental pedestrian bridge were analysed. The results show that further analyses and more data processing are required to evaluate whether the model is a good approach to account for human-induced vibrations including HSI.
