Post-disaster Damage Assessment of Bridge Systems
| 项目名称： | Post-disaster Damage Assessment of Bridge Systems |
| 摘要： | Leveraging recent advances in artificial intelligence, a novel signal processing technique will be developed to build a surrogate model for an accurate prediction of engineering demand parameters of interest (e.g., peak column drift ratio). The epistemic uncertainty of the surrogate model will be quantified and integrated with other uncertainties in performance-based engineering methodology so that rapid condition assessment and loss estimation can be provided in a probabilistic manner. The proposed framework will be first verified through the data generated using finite element analyses, and its reliability will be validated through proof-of-concept experiments. The intended outcome of the project is the development of a sensor-based framework for reliable post-disaster damage assessment of bridge systems. This technology is expected to automate the process of damage detection, and to assess and identify risks associated with each bridge immediately after a natural disaster. Practical guidelines to implement the methodology will be prepared, with input from the industry collaborators. |
