Previous studies on moral judgment have assumed that the trolley and footbridge dilemmas (Thomson, 1985) reflect utilitarian and deontologist thinking, respectively. However, on the basis of the “intervention myopia” hypothesis (Waldmann & Dieterich, 2007) and recent findings in analyses of moral dilemmas (Nakamura, 2011), the current study led a somewhat paradoxical prediction: An effect of th...

Many footbridges have natural frequencies that coincide with the dominant frequencies of the pedestrian-induced load and therefore they have a potential to suffer excessive vibrations under dynamic loads induced by pedestrians. Some of the design standards introduce load models for pedestrian loads applicable for simple structures. Load modeling for more complex structures, on the other hand, i...

One application in structural engineering is measuring the movement of suspension bridges. Under unfavourable wind conditions or heavy traffic loads cable suspension bridges may move up to a few metres. Therefore a positioning system used to monitor bridge movements can provide valuable information. For such monitoring applications it is desirable for the positioning system to deliver equal pre...

This work validates the simplified theoretical, analytical and numerical models used in preliminary design stage of 516 Arouca footbridge over River Paiva (Portugal), world's longest suspension footbridge. The were to define configuration bridge under static loading eigenfrequencies excited dynamic loading. three-dimensional finite element model detailed is briefly described. paper also present...

To perform a realistic reliability analysis of a complex cable-stayed steel footbridge subject to natural hazard and corrosion, this article addresses a rational process of modeling and simulation based on identification, model updating, and validation. In particular, the object of this study is the Ponte del Mare footbridge located in Pescara, Italy; this bridge was selected as being a complex...

This paper presents a probabilistic damage identification study on a full-scale structure, the Dowling Hall Footbridge, through a Bayesian finite element (FE) model updating. The footbridge is located at Tufts University and is equipped with a continuous monitoring system that measures its ambient acceleration response. A set of data is recorded once every hour or when triggered by large vibrat...

Moral psychologists have shown that people’s past moral experiences can affect their subsequent moral decisions. One prominent finding in this line of research is that when people make a judgment about the Trolley dilemma after considering the Footbridge dilemma, they are significantly less likely to decide it is acceptable to redirect a train to save five people. Additionally, this ordering ef...

In this paper, effects of changing ambient temperatures on finite element (FE) model updating of the Dowling Hall Footbridge are investigated. The Dowling Hall Footbridge is located on the Tufts University campus in Medford, Massachusetts. The footbridge is equipped with a continuous monitoring system that records vibration and temperature of the bridge once an hour or when triggered by large v...

Many moral psychologists have proposed that the difference between people’s moral judgments about the Trolley and Footbridge dilemmas can be explained by their differing emotional responses to the dilemmas. In two experiments, we tested this explanation by presenting the dilemmas and measuring participants’ reactions using a self-report emotion measure (PANAS-X). As might be expected, participa...
