| Abstrakt: |
An innovative design concept for a cable-stayed footbridge has been studied, alternative to the classical Pratt or Warren truss-girders type footbridges. This footbridge is provided with an arch (so called “Rainbow”) that is detached from the whole structure and carrying the cables to support the deck, making the footbridge a two-span structure. The idea is providing a footbridge with the features necessary to produce energy by itself, by means of piezoelectric sensors placed at the floor and activated by the pressure of the foot and photovoltaic panels to supply the lifts for disabled persons. Two mechanical systems are placed right under the deck, in proximity of the maximum sagging moment of the two spans and designed to develop energy from the vibrations induced by the pedestrians and store into battery chargers or used for lighting. |
