SHM Campaign on 138 Spans of Railway Viaducts by Means of OMA and Wireless Sensors Network fact, bridges and viaducts represent key components of the transportation network, and therefore they increasingly draw infrastructure managers’ attention. The present work is the result of a project carried out by Politecnico di Milano, consisting of a large experimental campaign conducted on a se

Effect of Damage on Vibration Characteristics of Reinforced Concrete Deck Slabs in an Existing Steelck slabs. An investigation using ambient vibration measurement with eleven sensors in a deck panel was conducted to study the effect of damages on vibrational characteristics and dynamic parameters of the deck slabs of a real bridge. The investigation was carried out at three different deck panel lo

Assessing Structural Health State by Monitoring Peridynamics Parameters in Operational Conditionsctural Health Monitoring (SHM). In particular, the paper aims to exploit PDs for SHM and damage characterization of the built environment, at the structural scale, in operational conditions (i.e., without input sources). The reasons behind this study rely on the possibility to use PDs to emulate ver

Impact Damage Identification Using Chirped Ultrasonic Guided Waves for Health Monitoring of CFRP Vehr, the barely visible impact damages (BVIDs) in CFRP laminates may cause a significant degradation in the performance, seriously affecting the safety of daily use. Hence, structural health monitoring (SHM) systems that can detect the BVIDs in mobilities are urgently needed. In this research, we atte

Bayesian Model Updating of a Simply-Supported Truss Bridge Based on Dynamic Responses FFT method was used to perform the modal identification obtained from field tests, and the Transitional Markov Chain Monte Carlo (TMCMC) algorithm is employed to generate samples. Although updating as many parameters as possible is the ideal model update process, it is not practical to identify all

Vibration-Based Method for Structural Health Monitoring of a Bridge Pier Subjected to Environmental system is developed to define new modal parameters to be monitored. Parameters from OMA make it possible to characterize the structure using experimental modal analysis (EMA). The method is applied to a bridge pier subjected to scour. Indeed, a prestressed concrete, motorway bridge on A71 in France
