Lateral vibration of footbridges under crowd-loading: Continuous crowd modeling approach [PDF]

, 2007
International audienceIn this paper, a simple 1D crowd model is proposed, which aim is to properly describe the crowd-flow phenomena occurring when pedestrians walk on a flexible footbridge.

Airborne 1O2 Delivery via a Superhydrophobic Dressing as a Pathway to Next‐Generation Wound Therapies, an in Vivo Murine Burn Model Study

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the SH bandage placed on an infected burn wound and its role in wound healing. A superhydrophobic PDMS membrane coated with the PS verteporfin is placed over the wound area and illuminated with a red laser at 690 nm, generating airborne 1O2 above the tissue.

Footbridge Response On Single Pedestrian Induced Vibration Analysis

, 2009
Many footbridges have natural frequencies that coincide with the dominant frequencies of the pedestrian-induced load and therefore they have a potential to suffer excessive vibrations under dynamic loads induced by pedestrians. Some of the design standards introduce load models for pedestrian loads applicable for simple structures.

Control of pedestrian-induced vibrations of long-span bridges

Structural Control and Health Monitoring, 2006
Sealed tuned liquid column dampers, with a gas-spring effect taken into account are ideally suited to increase the effective structural damping of bridges vibrating in the low-frequency band, up to about 5 Hz. Modal tuning in analogy to the classical mechanical damper followed by fine-tuning in state space, render the parameter optimal and the control ...

Damping Of Pedestrian‐Induced Bridge Vibrations By Tuned Liquid Column Dampers [PDF]

PAMM, 2004
AbstractThe excessive lateral vibrations of Londons Millenium Bridge and the Toda Park Bridge in Japan due to a large number of crossing pedestrians have raised an unexpected problem in footbridge constructions. Secondary tuned structures, like the conventional tuned mass damper (TMD) or the tuned liquid damper (TLD) were installed to the bridge in ...

Experimental Study of Bending and Torsional Effects in Walking-Induced Infrastructure Vibrations: The Pasternak Footbridge

Infrastructures
Slender, lightweight and modern footbridges are particularly susceptible to vibrations induced by pedestrian activity. While extensive research has focused on vertical and lateral forces produced by walking, torsional moments generated by eccentrically ...
