Load models that account for Human-Structure Interaction (HSI) may be preferable to accurately predict the dynamic response of lightweight footbridges subjected to pedestrian actions. Representing each person within a crowd may not be practical in engineering design calculations as time-variant models with a large number of degrees of freedom...

Stay cables exhibit both great slenderness and low damping, which make them sensitive to resonant phenomena induced by the dynamic character of external actions. Furthermore, for these same reasons, their modal properties may vary significantly while in service due to the modification of the operational and environmental conditions. In order to...

Human-Structure Interaction (HSI) may influence the dynamic behaviour of Fibre Reinforced Polymer (FRP) footbridges due to the lightweight nature of composite materials. Hence, load models that account for HSI should be applied to accurately predict vibration levels on these pedestrian structures. This paper proposes a model to assess the...

Passive damping devices are widely installed to control the vibration level of stay cables of bridges induced by wind action. The design of passive damping devices must ensure the performance for the all the life-cycle of the structure. In this sense, the design should consider the changes of the pre-fixed parameters and environmental...
