A Deep Learning-Based Framework for Damage Detection With Time Series

Abstract: Natural hazards have caused damages to buildings and infrastructures and economic losses in many countries. Immediate emergency response requires accurate damage detection. In recent studies, advances in deep learning approaches have put forward the development of data-driven damage detection. However, these proposed approaches can successfully classify damaged samples into different damage states without quantifying them. Therefore, we propose a deep learning-based framework for damage detection, which compri… Show more

“…The algorithm is verified with the vibration responses of two beam structures and a long-span cable-stayed bridge and can reliably detect and quantify various damage scenarios. Yang et al [18] proposed a novel damage recognition network designed as an encoder-decoder-encoder combination for detecting damage in a building. They trained the model using the Fourier spectra of acceleration signals in the undamaged state to recognize the pattern that is related to damage.…”

“…We trained a Seq2Seq model with only undamaged signals to learn their representations and hence the model's reconstruction results are supposed to deviate when inputting damaged signals. The probability of damage according to the extent of deviation is defined as suggested in [18]:…”

“…Damage assessment based on sensor data, such as acceleration responses, may be improved with the use of vibration-based models, which give potential solutions [2]. These models account for shifts in vibration characteristics that occur due to damage and identify aspects in vibration data that are related to the occurrence of damage.…”

“…In the literature, a Fourier transform-based denoising approach has been employed to eliminate noisy components in stock market index data, particularly those that adversely impact the model’s performance in predicting closing prices for the S&P500, KOSPI, and SSE indices ( Song, Baek & Kim, 2021 ). In addition, the Fourier transform has also been used to eliminate the noise in the signals collected from the sensors for the damage detection module ( Yang et al, 2021 ). In these studies, various deep-learning approaches were employed to develop models on denoised data.…”
