Intelligent Fiber Optic Systems Corporation (IFOS) is developing a Fiber Bragg Grating (FBG) integrated Structural Health Monitoring (SHM) sensor system capable of load monitoring as well as detecting, locating and quantifying cracks and de-laminations in composite structures such as smart composite wings with embedded FBG sensors. This paper describes an approach that enables analysis of complex...
Bridge vibration frequency is a measure of the overall state and structural damage will inevitably lead to changes in frequency. Based on this approach, we realized the bridge health monitoring system, introduced the bridge health monitoring system design approach, the data collection process and data analysis. Test proved that the vibration frequency of the bridge on the health status of the bridge...
Structural Health Monitoring (SHM) systems have been used with many important structures to enhance the public safety and to reduce the economical losses. Wireless Sensor Networks (WSN) is an emerging technology which can be deployed with SHM applications. However, some system requirements have been overlooked in the current WSN designs for SHM applications. Therefore a complete analysis in system...
In the last years an increasing interest has been devoted to all the topics related to security and safety of people. Particular attention has been paid to health monitoring of large civil structures hosting lot of people, like high-rise buildings and stadia. The vast scientific literature confirms the possibility to relate structural health to the evolution of modal parameters, often reaching the...
This paper presents a structural health monitoring system for monitoring, with reduced visual impact, one historical building structure. The system is based on fiber Bragg gratings and comprises 19 displacement sensors and 5 temperature sensors. All the sensors were custom made according to the monitoring points' characteristics. The results obtained over the first year of monitoring are presented...
