An Estimation of Pedestrian Action on Footbridges Using Computer Vision Approaches

open access: yesFrontiers in Built Environment, 2019
Vibration serviceability of footbridges is important in terms of fitness for purpose. Human-induced dynamic loading is the primary excitation of footbridges and has been researched with traditional sensors, such as inertial sensors and force plates ...

Dynamic behavior of a cable-stayed footbridge depending on the calculation accuracy

open access: yesActa Polytechnica CTU Proceedings
Footbridges are analyzed in terms of dynamic response for pedestrian comfort. This problem is solved mainly on light and at the same time rigid constructions, which are easily oscillated by pedestrian load.

Design of an emergency footbridge

open access: yesWIT Transactions on The Built Environment, 2014
This paper will describe the design of a temporary emergency floating footbridge, to be made when the infrastructure is destroyed by a flood, hurricane, tsunami or any other disaster. The bridge is made of identical floating modules. The modules are composed of prefabricated elements: two trusses, a pontoon and the footpath.
