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

Shell-supported footbridges [PDF]
Curved 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

Pedestrian load models of footbridges [PDF]
MATEC Web of Conferences, 2017 The increase of vibration problems in modern footbridges shows that footbridges should no longer be designed for static loads only. Not only natural frequencies but also damping properties and pedestrian loading determine the dynamic response of ...

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

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

Visualization of crowd synchronization on footbridges [PDF]
Journal of Visualization, 2009 This paper proposes a framework for the visualization of crowd walking synchronization on footbridges. The bridge is modeled as a mass-spring system, which is a weakly damped and driven harmonic oscillator. Both the bridge and the pedestrians walking on the bridge are affected by the movement of each other.

Experimental and Numerical Study on Dynamics of Two Footbridges with Different Shapes of Girders
Applied Sciences (Switzerland), 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-

Modelling Construction of Footbridges with Cables
Footbridge 2017 Berlin - Tell A Story: Conference Proceedings 6-8.9.2017 TU-Berlin, 2017 <p>The usual moderate dimensions of footbridges allow design architects (and sometimes engineers) to provide such structures with capricious forms. Under such circumstances, the analysis of the service state is usually very thorough, devoting to the study of the construction stages much less attention.

Study of pedestrian-induced vibrations on timber footbridges
Maderas: Ciencia y Tecnología, 2014 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 ...
