The term "Structural Health Monitoring (SHM)" refers to the real-time monitoring and alerting of structures state-of-health. The primary objective of SHM is to improve safety and reliability of civil infrastructure by detecting damage before it reaches a critical state and to enable rapid post-event (e.g., earthquake) assessment. In addition, the data from afforded SHM systems are used to validate design assumptions and codes, to predict response for large excitations, to calibrate analytical models, and to develop instantaneous damage and loss maps. As part of the Emirate of Abu Dhabi Seismic Hazard and Risk Assessment (ADSHRA) project, several unique and prestigious structures in Abu Dhabi were installed with state-of-the-art SHM systems. Typical systems are composed of up to 30 accelerometers within the building, a wind velocity/direction sensor at the roof, and a three-component downhole accelerometer near the building footprint. Data from these systems are all time-synchronized and recorded continuously at 200sps in real-time. A real-time data processing and analysis software package is developed to observe and display the dynamic characteristics (e.g., modal frequencies, damping ratios, and mode shapes) and responses (e.g., accelerations, velocities, displacements, and inter-story drifts) of the structures and their time variations. Since most of the SHM data are due to ambient forces (i.e., low amplitude vibrations with very low signal-to-noise ratios), advanced signal processing and system identification techniques, based on statistical signal processing and stochastic filtering theories, are used for data processing and analysis. In April 2013, two large earthquakes struck the region of southern Iran. Although very far away and producing seemingly very low levels of shaking, both events resulted in mass evacuations across many cities throughout the Gulf countries including Abu Dhabi. One obvious explanation for the understandable widespread reaction is that the region is simply not use to seismic activity. However, analyses of data recorded in several tall Abu Dhabi buildings during these events provides additional unique insight into human perception and structural response to prolonged vibrations of
