Mobile bridge integrity assessment

Within this work-in-progress, we aim to assess the structural integrity of bridges in the case of catastrophic events. Therefore, usually Vibration Measurement Systems (VMS) are used to extract the natural frequencies of bridges. Nevertheless, VMS in many cases are not available in a timely manner in areas struck by a disaster. In this work, we suggest how several commercial smart phones and their built in accelerometers can be used instead of VMS. By comparing the measurement results we show the feasibility of our approach.
