Generative Adversarial Networks for Structural Damage Diagnostics

  • Method and system for monitoring the health of civil structures and predicting damage
  • Deep-learning-based generative model can provide dynamic responses for conditions affecting a structure throughout its life cycle


The University of Central Florida invention describes deep-learning-based generative model methods—Generative Adversarial Networks (GAN)—for civil structural health monitoring and damage prediction. Damage diagnostic data is limited, as data collection can be costly and challenging or because there are not enough data from damaged areas to train detection models. Using information collected from multiple structures, synthetic data samples can be generated by state-of-the-art GAN models and used to train damage diagnostic systems. These tools could aid engineers, stakeholders, and decision-makers (1) to perform diagnostics accurately and effectively on raw acceleration signals and (2) to be proactive rather than reactive in managing the life cycle of structures.
