CLOUD-BASED CYBER INFRASTRUCTURE FOR BRIDGE MONITORING

This paper describes a cloud-based cyber infrastructure for the management of information involved in bridge monitoring applications. Recent years have seen an emergence and increasing use of sensor technologies for bridge monitoring. In addition to the measurement data from the sensors, bridge monitoring and management systems require many different types of information including bridge geometries, engineering analytical models and the metadata about the sensors. In this study, we employ cloud computing services and have implemented a cloud-based cyber infrastructure platform to effectively manage the information involved in bridge monitoring applications. Furthermore, NoSQL database systems are deployed for scalable and flexible data storage. To facilitate interoperability, a bridge information model is designed based on open standards and bridge engineering analysis and design tools. For demonstration purposes, the model of the Telegraph Road Bridge located in Michigan and the sensor data collected on the bridge are employed to illustrate the use of the cyber infrastructure system for bridge monitoring.
