ABSTRACT
A new metro bridge was constructed across the Golden Horn, Istanbul. The bridge consists of 2 approach viaducts, a cable-stayed bridge with a main span of 180 meters and a swing bridge. A metro station is situated in the center of the main bridge. The deck of the cable-stayed bridge and the swing bridge are designed as steel structures. The bridge was equipped with a sophistic structural health monitoring solution, which will be delivered by VCE- Vienna Consulting Engineers. The paper describes the solution proposed by VCE. It covers the development and design of the instrumentation and the system for the monitoring of the behavior, the performance and the condition of the structure. The monitoring concept consists of 3 subtasks:
Initial measurements and investigations after completion of the structure.
Permanent structural health monitoring.
Portable equipment for periodic assessment.
A special focus is on the data management part, which includes data archiving, data analysis and the presentation of the monitoring data to the operation personal and to the client. Apart from the compulsory control room devices the system will include a web-user interface, which allows a secure access to the monitoring data and results with mobile devices from anywhere and anytime.
