Abstract
A dynamic method for the damage evaluation of large bridges is developed by BVFA and Technical University Graz. The method is a combination of dynamic in-situ tests and dynamic calculations. The basic idea is to detect damage to bridges via changes of the dynamic parameters. The steps in the process are dynamic in-situ testing, mathematical modelling, fitting of the mathematical model to the test results and sensitivity investigations. The development of the method is presented by discussing the history of the process. Further, the steps are discussed, giving references to detailed information and some examples from past projects. The latest investigations were started in October 1988 on five bridges on the Brenner motorway. The tests were finished in April 1989 and analysis of measurements is still under way. More detailed results will soon be available.
