Experimental Tests and Numerical Analyses for the Dynamic Characterization of a Steel and Wooden Cable-Stayed Footbridge

open access: yesInfrastructures, 2023
Vibrations are an issue of increasing importance in current footbridge design practice. More sophisticated footbridges with increasing spans and more effective construction materials result in lightweight structures and a high ratio of live load to dead ...

Design of a Semiactive TMD for Lightweight Pedestrian Structures Considering Human–Structure–Actuator Interaction

open access: yesActuators, 2022
Lightweight pedestrian structures constructed with high strength-to-weight ratio materials, such as fiber-reinforced polymers (FRP), may experience large accelerations due to their lightness, thus overcoming the serviceability limit state.

Application of an Artificial Fish Swarm Algorithm in an Optimum Tuned Mass Damper Design for a Pedestrian Bridge

open access: yesApplied Sciences, 2018
Tuned mass damper (TMD) has a wide application in the human-induced vibration control of pedestrian bridges and its parameters have great influence on the control effects, hence it should be well designed.

Some relevant aspects of footbridge vibrations [PDF]

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering, 2002
Considering the contemporary structural inaterials that are becoming more resistant, having higher strength to weight ratio, and the fact that live load of footbridges is low, the design based on static analysis only, respecting ultimate limit states ...

Influence of anchoring and bracing system on dynamic characteristics of façade scaffolding [PDF]

open access: yesArchives of Civil Engineering, 2023
The basic dynamic characteristics of façade scaffolding are natural frequencies of vibrations and corresponding mode shapes. These properties affect the scaffolding safety, as well as comfort and safety of its users.

Vibration Serviceability of the Aberfeldy Footbridge under Various Human-Induced Loadings

open access: yesMaterials, 2023
Developing new structural materials, such as composite materials, has provided many opportunities in bridge engineering. Among these materials, glass-fiber-reinforced polymers (GFRPs), in particular, have found applications in footbridges. However, some of the commonly recognized advantages of GFRPs, such as the high values of the strength/weight ratio,

Vibrational performance of pedestrian bridges due to human-induced loads. [PDF]

open access: yes, 1997
The vibrational performance of footbridges due to human-induced loads has been investigated, based on modal and pedestrian tests carried out on three prototype footbridges.

Evaluation and Prediction of Blast-Induced Ground Vibrations: A Gaussian Process Regression (GPR) Approach

open access: yesMining, 2023
Ground vibration is one of the most hazardous outcomes of blasting. It has a negative impact both on the environment and the human population near to the blasting area.

Human induced vibration of staircases: Measurements and analysis [PDF]

open access: yes, 2019
While there are numerous design guidelines for oscillations of floors, staircases have received comparatively less attention. Dynamic testing of existing staircases can improve understanding of their behaviour and lead to more accurate methods for predicting accelerations in service.

Measuring human-induced vibrations of civil engineering structures via vision-based motion tracking [PDF]

open access: yes, 2016
We present a novel framework for measuring the body motion of multiple individuals in a group or crowd via a vision-based tracking algorithm, thus to enable studies of human-induced vibrations of civil engineering structures, such as floors and ...
