Although moral dilemmas such as the trolley and footbridge dilemmas (Thomson, 1986) have been widely employed to investigate the nature of moral reasoning, but their psychometric properties remain a mystery. In this study, 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001), and the correlation structure among the dilemmas was analyzed through factor analysis and stru...

Modern footbridges are often lively structures, characterized by natural frequencies that fall in the range of pedestrian activities, such as walking, running, and jumping. Therefore, serviceability assessment under human-induced excitation is crucial both at design stage during footbridge lifetime. This paper presents validates two different FE models an existing with very complex geometry: St...

Tensegrity structures are spatial reticulated structures composed of cables and struts. A tensioncompression equilibrium leads to lightweight systems that change shape through length changes in their members. Active members thus control several degrees of freedom simultaneously. Tensegrityring modules are transformable circuit-pattern modules. The linear combination of tensegrity rings has been...

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...

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...
