Assessing subway network ground borne noise and vibration using transfer function from tunnel wall to soil surface measured by muck train operation
(2019)During the operation of urban subway rail transit system, ground vibrations are generated that transmitted through the ground and cause vibrations in nearby buildings. The operation of these systems can be characterized ... -
A combined numerical/experimental prediction method for urban railway vibration
(2017)Railway-induced ground vibrations can cause negative effects to people/structures located in urban areas. One of the main sources of these vibrations is from the large vehicle forces generated when train wheels impact local ... -
The effect of railway local irregularities on ground vibration
(2015)The environmental effects of ground-borne vibrations generated due to localised railway defects is a growing concern in urban areas. Frequency domain modelling approaches are well suited for predicting vibration levels on ... -
Ground borne noise and vibration transfer function inside sensitive neo-classic buildings from Piraeus metro tunnel during TBM's operation
(2019)Attiko Metro S.A., in view of the additional development of Athens Metro network, has fully initiated the new extension of 7.6 km, for line 3 extension from Aghia Marina to Piraeus Dimotiko Theatre, towards “University of ... -
Model calibration of metsovo bridge using ambient vibration measurements from various construction phases
(2015)Available methods for structural model updating are employed to develop high fidelity models of the soil-foundation-structure of Metsovo bridge using ambient vibration measurements. The Metsovo bridge, the highest bridge ... -
Modelling the singular rail and wheel surface defect for predicting railway ground vibration
(2015)When undertaking a railway vibration assessment, the presence of singular defects on the rail and wheel surfaces significantly affects the ground vibration level. The objective of this paper is to analyse the most common ... -
Monitoring and assessment of vibration during construction of athens metro extention to piraeus
(2016)Environmental standards for the quality of life and safety of workers constitute a rigorous frame which should be respected during construction works of metro tracks. Monitoring techniques constitute a powerful tool to ... -
Online damage detection in plates via vibration measurements
(2015)In this work, we propose a new framework for the online detection of damage in plates via vibration measurements. To this end, a finite element model of the plate is handled by a recursive Bayesian filter for simultaneous ... -
Railway ground vibrations induced by wheel and rail singular defects
(2015)Railway local irregularities are a growing source of ground-borne vibration and can cause negative environmental impacts, particularly in urban areas. Therefore, this paper analyses the effect of railway track singular ... -
Uncertainty calibration of large-order models of bridges using ambient vibration measurements
(2014)A computational efficient Bayesian inference framework based on stochastic simulation algorithms is presented for calibrating the parameters of large-order linear finite element (FE) models of bridges. The effectiveness ... -
Vibration-based Damage Localization and Quantification Framework of Large-Scale Truss Structures
(2022)The use of structural health monitoring (SHM) systems on a regular basis is critical to achieve early damage detection, avoid unpredicted failures, and perform cost-effective maintenance planning. The main objective of ... -
Vibrations from rail traffic and mitigations measures for the reduction of railway noise
(2015)The present paper presents an analysis of the mechanism of propagation of vibrations from rail traffic and its effects to the surrounding land uses. First, the following issues are examined: levels of noise from rail traffic ...
