Effects of Vertical Ground Motion on Pedestrian-Induced Vibrations of Footbridges: Numerical Analysis and Machine Learning-Based Prediction

open access: yesBuildings, 2022
Current codes and guidelines for the dynamic design of footbridges often only specify the pedestrian-induced excitations. However, earthquakes may occur during the passing stage of pedestrians in earthquake-prone regions.

Pedestrian-Induced Vibrations of Footbridges: An Extended Spectral Approach

open access: yesJournal of Bridge Engineering, 2020
Abstract The vibration serviceability assessment of footbridges under pedestrian traffic requires a probabilistic approach considering the uncertainty in the dynamic behavior of the structure and t...

Parameter Calibration of a Social Force Model for the Crowd-Induced Vibrations of Footbridges

open access: yesFrontiers in Built Environment, 2021
A reliable prediction of the human-induced vibrations of footbridges relies on an accurate representation of the pedestrian excitation for different loading scenario. Particularly, the modeling of crowd-induced dynamic loading is a critical issue for the

Shear Lag Effects on Pedestrian-Induced Vibration and TMD-Based Vibration Control of Footbridges [PDF]

open access: yesStructural Engineering International, 2022
The shear lag effect (SLE) is one of the vital mechanical characteristics of structures with thin-walled box sections. While most existing studies of the SLE focus on the static response of footbridges, pedestrian-induced vibration deserves more attention since it represents the actual response of footbridges during their practical service process.

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.

Vibration serviceability of footbridges under human-induced excitation : a literature review [PDF]

open access: yes, 2004
Increasing strength of new structural materials and longer spans of new footbridges, accompanied with aesthetic requirements for greater slenderness, are resulting in more lively footbridge structures.

Identification of Dynamic Parameters of Pedestrian Walking Model Based on a Coupled Pedestrian–Structure System

open access: yesApplied Sciences, 2021
As human occupancy has an enormous effect on the dynamics of light, flexible, large-span, low-damping structures, which are sensitive to human-induced vibrations, it is essential to investigate the effects of pedestrian–structure interaction.

Experimental Tests and Numerical Analyses for the Dynamic Characterization of a Steel and Wooden Cable-Stayed Footbridge

open access: yesInfrastructures, 2023
Vibrations are an issue of increasing importance in current footbridge design practice. More sophisticated footbridges with increasing spans and more effective construction materials result in lightweight structures and a high ratio of live load to dead ...

Optimal actuator placement for control of vibrations induced by pedestrian-bridge interactions

open access: yesMathematics in Applied Sciences and Engineering, 2023
In this paper, an optimal actuator placement problem, with a linear wave equation as the constraint, is considered. In particular, this work presents the framework for finding the best location of actuators depending upon the given initial conditions ...

Vibration Analysis of Low Height-to-Span Ratio Pedestrian Bridge under Human-Induced Excitation

open access: yesAdvances in Civil Engineering, 2023
Driven by the aesthetic pursuit of the urban landscape, pedestrian bridges become longer, lighter, and slender, which may be susceptible to unacceptable vibrations induced by human activities.
