| Brief Description of Research Project | This research aims to present data-driven models that determine bridge element weights towards overall bridge health, considering bridges in different operational and environmental conditions. The specific objectives for the research aim are: 1. Create bridge breakdown structures that define bridge elements in hierarchical structural relationships by bridge components 2. Analyze element condition data and National Bridge Inventory (NBI) condition rating data for deterioration curves at both levels of bridge elements and components 3. Apply a similarity measure to analyze the time-varying similarities of deterioration curves between a bridge element and its upper-level bridge component 4. Identify weight-changing factors that are hypothesized to change bridge element weights across bridges in different operational and environmental conditions and formulate their effects on individual bride element weights 5. Evaluate bridge element weights derived from this project |
