Generally footbridges for pedestrians are designed so that the pedestrians may be regarded as static load. Some such footbridges are sometimes found to produce uncomfortable Vibration by passage of pedestrians. This paper describes the characteristics of dynamic fluctuation of the pedestrian's load, the...

Slender footbridges are often highly susceptible to human-induced vibrations, due to their low stiffness, damping and modal mass. Predicting the dynamic response of these civil engineering structures under crowd-induced loading has therefore become an important aspect of the structural design. The excita...

Lively footbridges: overview and perspectives for the development of crowd and structure monitoring systems Modern pedestrian bridges are very often lively structures: this feature is due, on one hand, to the increasing strength of materials and the design trend ...

Currently, several all-GFRP footbridges are located above railway tracks that were monitored by other researchers, e.g. the Lleida Bridge with double-tied arch in Spain [7], the Dover Seawall Bridge in UK consists of two simply supported trusses [8], the Bradkirk Bridge in UK with the ...
Human-induced vibrations on footbridges have gained a lot of attention in recent years, since the community demands for more aesthetically pleasing and slender bridges [1], [2], [3]. Moreover, improvements in materials, design methods, building techniques and the involvement of architects led to...
The improvement of construction materials together with the current aesthetic requirements has led the modern footbridges to a continuous increase in their slenderness. For this reason, the design of their structural systems is mainly conditioned by its dynamic response under pedestrian action. For long...
Often applied at design stage, they enable designers to asses the efficiency and suitability of various building/structure layouts. In spaces where large crowds are expected, they can be crucial in reducing the likelihood of injury or death resulting from a crowd panic or flight response [6]. ...
