ABSTRACT

ABSTRACT: Bridge rehabilitation to increase the service life and to reduce the maintenance costs becomes more and more important for steel railway bridges. Thus assessment procedures are required that comprise insight and comprehensive knowledge. This can be achieved by the combination of theoretical and experimental investigations by monitoring. For the application of technical monitoring on steel railway bridges various systems to particular monitoring tasks exist. The final choice, which system is most beneficial, depends on the aim of the monitoring measure. In this paper monitoring is defined and monitoring systems are introduced. Further the implementation of monitoring in the service life analysis for steel railway bridges and a draft of a risk analysis for the evaluation of the benefit of the appliance of monitoring is presented.
