Abstrakt:

The test and maintenance of existing bridges require a large part of the available resources. In order to analyse the bridges faster and economically the Institute for Structural Engineering at University of the German Armed Forces in Munich is developing a system, which enables the user to estimate the bending stiffness of a bridge without any documents of the structure. A shaker system will be developed, which will be installed temporally on the bridge. It will vibrate the bridge with selective frequencies. The response of the bridge will be measured and recorded at the same time. In the second step a procedure will be developed to obtain the bending stiffness of the bridges by means of the calculated modal parameters such as natural frequencies.
