Methodology: Conditional-Labeled Generative Adversarial Networks (GANs)
This section details the innovative conditional-labeled Generative Adversarial Network (GAN) approach. Unlike traditional supervised methods, this GAN framework allows for unsupervised damage detection and the generation of damage state measurements without requiring prior knowledge of the system's health. It leverages the training convergence behavior as a novel indicator of structural novelty, where slower convergence signifies greater structural changes. The GAN consists of a generator, which produces synthetic vibration data conditioned on damage states, and a discriminator, which differentiates between real and generated data. The architecture includes deep neural networks with convolutional layers to capture temporal dependencies, iteratively trained with the Adam optimizer.
Z24 Bridge Application: Real-World Validation
The methodology is rigorously validated on the Z24 Bridge dataset, a real-world benchmark for Structural Health Monitoring (SHM). This post-tensioned concrete highway bridge in Switzerland was subjected to 17 progressive damage scenarios over a year. The GAN processes ambient vibration response data, learning to generate synthetic signals for both healthy and damaged states. The convergence scores of the GAN during training serve as a damage-sensitive metric. The generated data is then evaluated using Principal Component Analysis (PCA) and a Support Vector Machine (SVM) classifier to assess its statistical similarity to real measurements and its effectiveness in distinguishing different damage states. This application demonstrates the model's ability to detect damage and generate realistic digital twin data for unknown damage conditions.
Key Findings & Impact: Unsupervised Detection & Digital Twinning
The study successfully demonstrates that the GAN framework can accurately detect damage and generate realistic structural response data for digital twinning. Faster convergence in training indicates stable structural conditions (healthy-to-healthy or same damage level), while slower convergence signals progressive or novel damage, acting as a crucial unsupervised indicator. The generated measurements exhibit statistical similarity to real data, confirmed by PCA, and enable high classification accuracy (over 90%) using an SVM. This approach provides a powerful tool for scalable infrastructure resilience by enabling pattern recognition and machine learning data generation, even in data-scarce scenarios or when new damage states emerge, without the need for prior labeling. The potential for multi-class damage detection is also demonstrated.
