Abstract
En 中文
• A FEM-based two-level approach combining pattern matching and model updating for hierarchical damage detection. • Element grouping and automatic clustering techniques for identifying potentially damaged regions in the first level and reducing the dimensionality of subsequent problem. • Element damage assessment in the second level by model updating with pattern matching-determined iteration and one-at-a-time updating strategy to address challenges in model updating. • Pattern matching enhancement with recommendation algorithm to guide damage localization and parameter adjustment. • Validation through numerical simulations with the ASCE Benchmark model and experimental studies on the truss bridge model.
