More Information
Summary:Provided are a system to detect abnormal behavior and evaluating safety of a structure and a method thereof capable of easily estimating a continuous abnormal behavior time of the structure by combining and analyzing a time domain and a frequency domain from a high-frequency vibration response signal of the structure, and performing an abnormal behavior assessment in accordance to a self-learning and pattern recognition algorithm; determining the authenticity of the detected abnormal behavior whenever the abnormal behavior of the structure is detected; and easily estimating a damaged region around a sensor node.
