BRIMOS^® —
Bridge Monitoring System

BRIMOS® can be defined as a method for system identification and damage detection in bridges and other civil structures due to its dynamic response to ambient excitation such as wind, traffic and micro seismic activity.

BRIMOS® has been used for many years in the field of Structural Health Monitoring. The term Structural Health Monitoring in the mean of Ambient Vibration Monitoring comprises the recording of the dynamic behaviour by the use of measuring instruments as well as the evaluation and analysis of the measured signals. The fundamental tools of health monitoring are system identification - SI, damage determination and localization as well as safety assessment and the maintenance management for infrastructure.

The analysis provides the determination of the modal parameters, namely the structure's natural frequencies, its mode shapes and its damping coefficients. These parameters which are gained from the measurements represent the real condition of a structure and are used to update mathematical models of a structure or are simply compared to reference data from earlier measurements. The measurements are, however, so precise that they can offer reference data with a high qualitative value for every future evaluation method.
