Sensitivity Analysis for Pedestrian-Induced Vibration in Footbridges

open access: yesBuildings, 2022
This paper aims to provide a novel insight into the influence of uncertainties in system- and pedestrian-induced load parameters on the vibration response of footbridges. The study begins with a sensitivity analysis for the vertical vibration response of a representative footbridge to two loading cases: a single pedestrian and a crowd.

Experimental Assessment of Human–Structure Interaction in an Urban Pedestrian Footbridge with Multiaxial Dynamic Sensitivity [PDF]

open access: yesSensors
Recent advances in structural engineering have enabled lightweight and slender footbridges. However, these structures are often susceptible to excessive vibrations induced by pedestrian activities, primarily impacting urban footbridge serviceability ...

STUDY OF PEDESTRIAN-INDUCED VIBRATIONS ON TIMBER FOOTBRIDGESC

open access: yesMaderas: Ciencia y Tecnología, 2010
In Brazil, studies about pedestrian-induced vibrations on footbridges have been carried out since the early 1990s, for concrete and steel footbridges. However, there is no record of such studies and the Brazilian Standard NBR 7190 (1997) for the design of timber structures only presents design requirements for static loads, in the case of timber ...

Vision-Based Methodology for Characterizing the Flow of a High-Density Crowd on Footbridges: Strategy and Application

open access: yesInfrastructures, 2020
Obtaining pedestrian trajectories by a vision-based methodology is receiving increasing attention in the literature over recent decades. Within the field of study of human-induced vibrations on footbridges, practical challenges arise when collecting the ...

A Theory of Pedestrian-Induced Footbridge Vibration Comfortability Based on Sensitivity Model [PDF]

open access: yesAdvances in Bridge Engineering, 2021
AbstractPedestrian-induced footbridge vibration comfort level is a complex problem that has been studied for a long time. However, no consensus has been reached on a quantitative calculation index for assessing vibration comfort level. Only simple comfort limits, rather than specific relationships between comfort level and the vibration endurance ...

Use of Smartphone-Based Experimental Data for the Calibration of Biodynamic Spring-Mass-Damper (SMD) Pedestrian Models [PDF]

open access: yesSensors
In practice, the structural analysis and design of pedestrian systems subjected to human-induced vibrations is often based on simplified biodynamic models that can be used in place of even more complex computational strategies to describe Human-Structure

Experimental Evaluation of Pedestrian-Induced Multiaxial Gait Loads on Footbridges: Effects of the Structure-to-Human Interaction by Lateral Vibrating Platforms [PDF]

open access: yesSensors
The introduction of resistant and lightweight materials in the construction industry has led to civil structures being vulnerable to excessive vibrations, particularly in footbridges exposed to human-induced gait loads.

Vibration serviceability limit state of pedestrian bridges [PDF]

open access: yesGrađevinski Materijali i Konstrukcije, 2021
Modern conustructions of pedestrian bridges must satisfy functional and increasingly complex architectural requirements. In order to achieve the attractive design of pedestrian bridges, modern constructions generally differ from older, conventional ...
