Global Vibration Comfort Evaluation of Footbridges Based on Computer Vision [PDF]

open access: yesSensors, 2022
The vibration comfort evaluation is a control standard other than strength and deflection, but the general comfort evaluation method only considers the response of the mid-span position and does not consider the difference in the vibration response of ...

Seismic Assessment of Footbridges under Spatial Variation of Earthquake Ground Motion (SVEGM): Experimental Testing and Finite Element Analyses [PDF]

open access: yesSensors, 2020
In this paper, the seismic assessments of two footbridges, i.e., a single-span steel frame footbridge and a three-span cable-stayed structure, to the spatial variation of earthquake ground motion (SVEGM) are presented.

Shell-supported footbridges

open access: yesCurved and Layered Structures, 2020
Architects and engineers have been always attracted by concrete shell structures due to their high efficiency and plastic shapes. In this paper the possibility to use concrete shells to support footbridges is explored. Starting from Musmeci’s fundamental

Vibration Serviceability of Footbridges Made of the Sustainable and Eco Structural Material: Glued-Laminated Wood. [PDF]

open access: yesMaterials (Basel), 2022
In this paper, dynamic analyses of two untypical, modern footbridges made of glued-laminated timber are presented. One of them is among the longest cable-stayed bridges for pedestrians in the world, made of such a structural material. Both structures are

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.

City of Skywalks: Exploring Hong Kong’s Public Space and Power of Discourse from Footbridges

open access: yesSocial Sciences, 2022
As a public space and building, the footbridge is not just a physical concrete building but also carries people’s life experiences and beliefs. In Hong Kong, however, footbridges are a joint product of the government and property developers to control ...

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

Vibration Serviceability of Footbridges: Classical vs. Innovative Material Solutions for Deck Slabs. [PDF]

open access: yesMaterials (Basel), 2020
In this study, the human-induced dynamic performance of modern footbridges equipped with either classical reinforced concrete (RC) or innovative glass fiber-reinforced polymer (GFRP) composite deck slabs were investigated and compared.

Evaluation of TMD Performance in Footbridges Using Human Walking Probabilistic Models

open access: yesVibration, 2021
Footbridges are generally slender and lightweight structures with low stiffness, designed to support dynamic loads generated by crowds. Therefore, these structures are exposed to vibration problems related to the resonance of human walking step ...

Experimental and Numerical Study on Dynamics of Two Footbridges with Different Shapes of Girders

open access: yesApplied Sciences, 2020
The paper presents the experimental and numerical results of the dynamic system identification and verification of the behavior of two footbridges in Poland. The experimental part of the study involved vibration testing under different scenarios of human-
