Abstract
We present a method for damage detection and localisation based on multiple-input finite impulse responses. A validation is carried out using measurement data obtained for a girder mast structure. The damage localisation using output-only vibration measurement data of beam-like structures has been a research topic for a long time and many methods have been developed to tackle the problem. However, the identification of finite impulse response filters with multiple inputs has not yet been covered in great detail in the context of these SHM methods. To localise structural damage, first the healthy structure is dynamically excited and finite impulse filters are derived using acceleration sensor data. In this process, we use multiple adjacent sensors as an input to derive the impulse response on a local level in the girder mast structure. The derived filters are applied to obtain an estimation of the transient response for healthy as well as damaged states. Residual signal energies between measured and predicted data are calculated, which increase locally when structural damages occur, enabling the localisation. The outlined damage localisation method, which solely relies on finite impulse responses as an output-only model of the structure, yields promising results in experimental validation.
