Hurst exponent footprints from activities on a large structural system

► First application of Hurst exponent based event characterisation of a full-scale experiment on large structures. ► First application of Hurst exponent based characterisation of sensor location and sensor malfunction. ► Successful application of windowed Hurst estimates for system monitoring. ► Demonstration of rich multifractality of the disparate activities. ► Establishing the potential of Hurst exponent measurement in monitoring and quantitatively comparing events from output-only conditions.
