This paper describes the work involving a real implementation of an active control system to reduce vibrations in a “lively” footbridge located at FEUP. This structure has some natural frequencies around 2Hz which can be easily excited by some pedestrian activities. Although the levels of vibration may not be considered excessive according to some design codes, this footbridge experiments regul...

We investigated whether and why the use of a foreign language influences moral judgment. We studied the trolley and footbridge dilemmas, which propose an action that involves killing one individual to save five. In line with prior work, the use of a foreign language increased the endorsement of such consequentialist actions for the footbridge dilemma, but not for the trolley dilemma. But contra...

This paper proposes a mathematical model and a computational approach to study the complex multiphysical non linear coupled system that results from the interaction between a moving platform and the pedestrians who walk on it. The described method is based on the mathematical and numerical decomposition of the coupled system into two subsystems and on the two-way interaction between them. In pa...

The suspension footbridges are very flexible due to their geometrical structure; hence they may face severe vibration problems induced mainly by natural forces and pedestrians crossing. By exceeding a certain limit, these vibrations can disturb the serviceability of the bridge as well as health and safety of the structure and pedestrians. Therefore, standard design guidelines are sets of recomm...

This paper presents the material and process-related research that underpinned realisation of Parque de Castilla Footbridge in Madrid 2016, going from laboratory to industrial scale. The fibre-reinforced cement-based composite was first developed tested a small-scale particle bed printer focusing on evaluating influence process mechanical response density printed parts. solution then upscaled f...

In the urban landscape, footbridges appeared along with development of urbanization through implementation more complex spatial structures. The introduction transport transit to cities or sometimes gravity towards important communication routes imposed their construction in order ensure pedestrians’ safety and smooth flow traffic. aim study is determine how an overpass city Trabzon used by peop...
