Fiber reinforced polymeric composites can be employed for the construction of structures that are highly durable and easy to fabricate. At EMPA, a prototype footbridge with girders and deck made of pultruded composite sections has been designed and constructed. For thin-wall pultruded sections such as I-beam or T-beam, delaminations can form easily at the web/flange junction. If the delaminatio...

This paper reports a parametric study on the influence of serviceability limit state design requirements material consumption and self-weight web-core sandwich panel FRP composite footbridges. It describes initial process typical footbridge, focussing relevance various checks overall at given slenderness. is clear that over wide range input parameters, only SLS are relevant for this bridge type...

It is generally accepted that having a proper river crossing point has positive effect on rural inhabitants. Such points would increase the ability of communities to access their social services, markets, jobs, and thereby lead raising standard living. In line with this objective,Rwanda been promoting construction pedestrian footbridges in areas, different partners, have already constructed. ve...

We tested if post-decisional emotions of regret, guilt, shame, anger, and disgust can account for individuals' choices in moral dilemmas depicting the choice of letting some people die (non-utilitarian option) or sacrificing one person to save them (utilitarian option). We collected participants' choices and post-decisional emotional ratings for each option using Footbridge-type dilemmas, in wh...

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...

Though scholars have speculated for centuries on links between individuals' social class standing and approach to moral reasoning, little systematic research exists on how class and morality are associated. Here, we investigate whether the tendency of upper-class individuals to exhibit reduced empathy makes them more likely to resist intuitionist options in moral dilemmas, instead favoring util...
