ABSTRACT
ABSTRACT: A team of Wroclaw University of Technology (WUT) is developing a monitoring system based on forced vibration tests. The tests, repeated periodically, have as a main goal to identify and monitor the modal parameters of the structure. It is expected that on the basis of the changes of construction modal parameters some conclusions concerning structure condition can be drawn. Results of the modal tests of bridges can be also used in FEM models updating, in the serviceability and fatigue analyses. As a bridge excitation source a special eccentric-mass exciter has been built and tested in laboratory. A dedicated software created for test control, data acquisition and processing has been also described in the paper.
