ABSTRACT
Signal processing has gradually become an indispensable tool in the field of engineering for extraction of important information from raw signals. In civil engineering, many practical and robust nondestructive evaluation (NDE) techniques developed for assessment of structural performance involve two key components, namely: (1) data acquisition and (2) signal processing and interpretation. Although the use of vibration measurements is a simpler and less costly method with respect to instrumentation system in comparison with infrared thermography, ground-penetrating radar, acoustic emission monitoring, and eddy current detection, a key factor for identifying damage precisely lies in having an appropriate data analysis method.
