Online Bridge Crack Monitoring with Smart Film
Smart film crack monitoring method, which can be used for detecting initiation, length, width, shape, location, and propagation of cracks on real bridges, is proposed. Firstly, the fabrication of the smart film is developed. Then the feasibility of the method is analyzed and verified by the mechanical sensing character of the smart film under the two conditions of normal strain and crack initia...
متن کاملSensors and Bridge Monitoring System
Rapid developments of structural sensing and control, data acquisition and processing, and computer technologies have made it feasible to monitor the structural health of large-scale structures in real time. SHM of large-scale infrastructures has increasingly attracted extensive interests from both fields of research and application. Based on recent research achievements of developing smart SHM...
متن کاملSteel bridge fatigue crack monitoring with broadband thin-film acoustic emission sensor
This paper presents a fatigue crack monitoring strategy termed close range acoustic emission (AE) signal sensing enabled by the use of low-cost thin-film AE sensor. In particular, flexible piezo paint has been used to make broadband thin-film AE sensors. This close-range AE signal monitoring method offers a promising new approach to AE-induced stress-wave sensing in the ultrasonic frequency ran...
متن کاملContinuous Monitoring of the Øresund Bridge: System and Data Analysis
The Øresund Bridge opened in July 2000. It is the most striking part of the fixed link across the Øresund connecting Copenhagen (Denmark) and Malmø (Sweden), which further includes a tunnel and an artificial island. The bridge is equipped with a PC-based continuous monitoring system, capable of measuring both static and dynamic quantities such as temperatures, wind characteristics, air humidity...
متن کاملOnline Deflection Monitoring System for Dafosi Cable-Stayed Bridge
A health monitoring system was designed and installed on Dafosi Bridge, the largest cable-stayed bridge across the Yangtze River in western China. This article briefly describes an online deflection monitoring system, the most important sensing subsystem of the health monitoring system. It can be divided into two major components, one for measurement, and one for control and data processing. Th...
