Human-induced vibrations of a curved cable-stayed footbridge

Journal of Constructional Steel Research, 2018
Abstract This paper investigates and compares the performances of two simulation models to predict the footbridge response to vertical pedestrian dynamic actions. For this purpose, a rational procedure based on experimental tests, identification, model-updating and simulation is addressed.

Control of human-induced vibration of an innovative CSBS–CSCFS

Journal of Constructional Steel Research, 2015
Abstract The large interior space requirement of public buildings leads to the development of an innovative Cable Supported Beam Structure–Concrete Slab Composite Floor System (CSBS–CSCFS). Field tests indicate that human activities can induce significant vibration of CSBS–CSCFS in some extreme cases, implying that to attenuate the dynamic response ...

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

Evaluation of human-induced vibration in floors of modular hospitals

Canadian Journal of Civil Engineering
Construction of modular hospitals has gained significant attention since the global pandemic. One important design requirement for hospitals that is critical for their safe operation is to control floor vibration. Floors in modular buildings are often more prone to vibration because they are lightweight and less restrained. This study first presents a

A framework for advanced methods of control of human-induced vibrations

SPIE Proceedings, 2012
The vibration serviceability of civil engineering structures under human dynamic excitation is becoming ever more critical with the design and redevelopment of structures with reduced mass, stiffness and damping. A large number of problems have been reported in floors, footbridges, sports stadia, staircases and other structures.

Control of human induced floor vibrations

2007
With the growing demand for open, column-free floor spaces and the advances in material strength, floor vibration serviceability criterion has been of growing importance within the past 20-30 years. All floor systems are flexible and when introduced to a dynamic loading respond in a vibratory manner.

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 ...
