Footbridge

Informes de la Construccion, 1964
La pasarela recientemente construida en Des Moines (EE. UU.), presenta la notable particularidad de tener sus accesos en curva y apoyarse sobre pilares de forma cilíndrica. Como el terreno no tenía suficiente resistencia de sustentación se tuvo que reforzar hincando pilotes para hormigonar, sobre ellos, la solera en la que descansa el montante ...

Analysis of technical condition of footbridges over the railways in danger of collapse [PDF]

MATEC Web of Conferences, 2019
The article presents issues related to the maintenance of small engineering structures, such as footbridges over railways. These types of objects, usually are simple both in structure and construction.

Experimental and Numerical Dynamic Properties of Two Timber Footbridges Including Seasonal Effects

International Journal of Civil Engineering, 2021
This paper deals with experimental and numerical dynamic analyses of two timber footbridges. Both bridges have a span of 35 m and consist of a timber deck supported by two timber arches. The main purpose is to investigate if the dynamic properties of the

A Statistical Approach for Modeling Individual Vertical Walking Forces

Applied Sciences, 2021
This paper proposes a statistical approach for modeling vertical walking forces induced by single pedestrians. To account for the random nature of human walking, the individual vertical walking force is modeled as a series of steps and the gait ...

Uncertainty-based approaches for the lateral vibration serviceability assessment of slender footbridges

, 2021
Slender footbridges with long spans and light materials may lead to serviceability problems in lateral vibrations due to walking pedestrians. The phenomenon, known as the “lock-in effect” occurs when the number of pedestrians on the footbridge reaches ...

Application of optimized spring–mass–damper pedestrian load models for vibration assessment of footbridges: numerical and experimental investigation of a cable-stayed system

Archives of Civil and Mechanical Engineering
This article explores the potential and accuracy of spring–mass–damper (SMD) pedestrian load modelling strategies for assessing human-induced vibrations of in-service footbridges.

A common framework for the robust design of tuned mass damper techniques to mitigate pedestrian-induced vibrations in lively footbridges

, 2021
The dynamic response of modern slender footbridges is usually sensitive to both the pedestrian actions and the uncertainties associated with their inherent structural behavior.

INTERVAL SERVICEABILITY ASSESSMENT OF FOOTBRIDGES [PDF]

Proceedings of the XI International Conference on Structural Dynamics, 2020
This paper studies serviceability assessment of footbridges through a non-deterministic approach. The parameters defining pedestrian-induced loading and the structural dynamic properties are characterized through possible ranges of variation. Starting from analytical expressions for the spectral moments of the structural response, the improved interval

Design Procedures for Footbridges Subjected to Walking Loads: Comparison and Remarks

The Baltic Journal of Road and Bridge Engineering, 2017
This paper aims at pointing out some misconceptions concerning the evaluation of the walking-induced dynamic response of footbridges, and their impact on design procedures. First, a review of the existing Code provisions is briefly presented.
