Human-Induced Vibrations on Two Lively Footbridges in Milan

Journal of Bridge Engineering, 2016
This article describes the results of extensive full-scale experiments carried out on two lively footbridges recently built in Milan, Italy. The objective of the study was to assess the dynamic characteristics of the bridges and the expected vibration level induced by pedestrians. A preliminary vibration analysis of the bridges revealed their potential

Human induced vibration vs. cable-stay footbridge deterioration

Smart Structures and Systems, 2016
In this paper, the possibility of using human induced loading (HIL) to detect a decrease of tension in the cable-stays of an existing footbridge is investigated. First, a reliable finite elements model of an existing footbridge is developed by calibration with experimental data.

UHPC Pedestrian Bridges and Measured Human Induced Vibrations

2017
The use of high strength materials in the design of pedestrian bridges leads to slender structures with decreased mass and low stiffness. The resulting low Eigen frequency makes the bridge more susceptible to human induced vibrations. As a consequence, user comfort may decrease significantly. In some designs it has been found that the geometry has been

Vibrational Response of Structures Exposed to Human-Induced Loads

Structures like pedestrian bridges, staircases and floors become lighter and more slender. As a consequence human-induced vibrations in resonance with the structure become increasingly important when considering the serviceability of a structure. The present paper describes the vibrational response using models for pedestrian loads and the accompanying

Footbridges: taking into account human induced vibrations.

2013
More and more slender, and with longer span, contemporary footbridges are submitted to new external conditions and surroundings. The issue of unexpected oscillations occurred during their opening day, for the Léopold Sédar Senghor bridge in Paris, and on a larger scale, for the Millennium bridge in London show that how nowadays, the study of the ...

Tuned-Mass-Damper optimization for human-induced footbridge vibrations

2013
The design of Tuned Mass Dampers (TMD) is becoming more and more usual in the current design of footbridges. This paper analyzes the optimal TMD design for mitigating pedestrian-induced vibrations in the most frequent loading scenarios, i.e. the single pedestrian modeled as a resonant moving harmonic load and the normal unrestricted pedestrian traffic,
