Structural Health Monitoring of Crusell Bridge

Abstract

<p>Crusell Bridge is a cable stayed bridge recently built in the city center of Helsinki. In the very beginning of the project the Client City of Helsinki decided to utilize the newest technology in all phases. The project was a pilot project in using Building Information Modeling (BIM) technology in design and construction and finally in monitoring as part of maintenance. In order to develop modern maintenance scheme, an intelligent monitoring system was designed and installed in the bridge. The monitoring system has been tested by a loading test and comprehensive test results have been compared with theoretical calculation analysis. The results verified the design and gave designers guidelines to specify alarming limits to monitoring system. The owner of the bridge will get a summary report from the maintenance system once per year.</p>
