Radar detection of pedestrian-induced vibrations on Michelangelo's David. [PDF]

PLoS ONE, 2017
This paper summarizes the results of a two-day dynamic monitoring of Michelangelo's David subject to environmental loads (city traffic and pedestrian loading induced by tourists visiting the Accademia Gallery).

Quantification of Dynamic Excitation Potential of Pedestrian Population Crossing Footbridges [PDF]

Shock and Vibration, 2011
Due to their slenderness, many modern footbridges may vibrate significantly under pedestrian traffic. Consequently, the vibration serviceability of these structures under human-induced dynamic loading is becoming their governing design criterion.

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

Infrastructures, 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 ...

STUDY OF PEDESTRIAN-INDUCED VIBRATIONS ON TIMBER FOOTBRIDGESC

Maderas: 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 ...

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

Sensors
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]

Sensors
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.

Pedestrian-induced lateral vibrations of footbridges:Experimental studies and probabilistic modelling [PDF]

, 2011
Denne afhandling omhandler vandrette fodgængerinducerede svingninger svarende til dem der bl.a. blev observeret på Londons præstigefulde gangbro, Millennium Bridge i året 2000 og Solferino-broen i Paris i 1999. I særdeleshed har den midlertidige lukning af førnævnte broer gjort ingeniører og arkitekter bevidste om de potentielle svingningsproblemer som

Vibration serviceability limit state of pedestrian bridges [PDF]

Građevinski 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 ...

MODELLING OF PEDESTRIAN-INDUCED LOAD IN SERVICEABILITY LIMIT STATE ANALYSIS OF FOOTBRIDGES

Facta Universitatis. Series: Architecture and Civil Engineering, 2022
The last few decades new trends in the design of pedestrian bridges have resulted in lighter and more slender structures. This leads to a reduction in natural frequencies and increased flexibility, and thus a greater possibility for structures to become ...
