Glass Suspension Footbridge: Human-Induced Vibration, Serviceability Evaluation, and Vibration Mitigation

Journal of Bridge Engineering, 2021
Abstract Glass suspension footbridges or glass-bottomed suspension footbridges, such as the Zhangjiajie Grand Canyon Glass Bridge in China, are increasingly constructed in scenic regions as tourist...

Classification of Human Induced Floor Vibrations

Building Acoustics, 2006
This paper summarizes results from vibration tests on floors. Classification of floors into five headings is given based on vibration characteristics. Suggested criteria and limiting values are proposed. These values are based on tests carried out on site and in laboratory conditions.

Simulation of Human Induced Vibration of a Lively Footbridge

2017
In the last years, the need for structures able to link the functional and aesthetic role has led to the design of new flexible footbridges. The low ratio between permanent and variable loads makes them more sensitive to dynamic loads, such as the forces transmitted by pedestrians.

An Intelligent Analysis Method for Human-Induced Vibration of Concrete Footbridges

International Journal of Structural Stability and Dynamics, 2020
It is essential to reliably predict the human-induced vibrations in serviceability design of footbridges to ensure the vibration levels to be within the acceptable comfort limits. The human-induced structural responses are dependent on the dynamic properties of structures and human-induced excitations.

Twin Rotor Damper for Human-Induced Vibrations of Footbridges

Journal of Structural Engineering, 2020
AbstractFootbridges often have a lightweight and slender design. As a result, they tend to be susceptible to human-induced vibrations.

Design of floor structures against human‐induced vibrations

Steel Construction, 2011
AbstractA simple method for designing floor structures against humaninduced vibrations is presented in a joint JRC‐ECCS publication, which was developed from two major European research projects supported by the Research Fund for Coal and Steel (RFCS).

Passive control of human-induced footbridge vibrations

2014
The design of Tuned Mass Dampers (TMD) in order to get the required pedestrian comfort 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

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

Design of slim‐floor construction for human‐induced vibrations

Steel Construction, 2015
AbstractThis paper presents a simplified design method for evaluating the vibration response of composite floors with slim‐floor beams. The methodology is amenable to hand calculations and is appropriate for floors with regularly spaced grids and vibrations that are occasioned by walking activities.

Vibrational Response of Structures Exposed to Human-Induced Loads

2018
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
