Pedestrian-Footbridge Dynamic Interaction: A Probabilistic Assessment of Vibration Serviceability [PDF]

open access: yes, 2016
Recent footbridges are characterized by long span, light materials and increasing slenderness, which make them more sensitive to dynamic forces induced by pedestrians.

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.

On the use of a simple tuned mass damper model for reducing the excessive vibration of tsunami evacuation suspension footbridge

open access: yesMATEC Web of Conferences, 2018
The suspension footbridges are commonly constructed in the rural area. The constructions method is relatively simple compared to other types of bridges, thus as consequence, the construction cost also becomes relatively cheaper.

Dynamic loading factors of individual jogging forces [PDF]

open access: yes, 2016
With increasingly popular marathon events in urban environments, such as in London and New York City, structural designers are faced with a great deal of uncertainty when assessing dynamic performance of bridges occupied and dynamically excited by people

Pedestrian and bicycle bridges as examples of safe collision-free road crossings

open access: yesMATEC Web of Conferences, 2017
Pedestrians are most at risk when they are crossing the road. This represents a significant proportion of all fatalities among pedestrians, amounting respectively to 50% in non-built-up areas and 75% in built-up areas.

Standards guidelines for human comfort tested on timber footbridges

open access: yesSemina: Ciências Exatas e Tecnológicas, 2011
Activities such as walking, running and jumping can produce undesirable dynamic excitations, which are a phenomenon that occurs due to pedestrian-induced dynamic forces whenever a footbridge features a natural frequency within stepping frequency ranges ...

Evaluation of human-induced vibration of continuous footbridges

open access: yesMATEC Web of Conferences, 2015
With the development of construction materials and the introduction of high strength steel and concrete, the human-induced vibration became a dominant criterion for the design of pedestrian bridges.
