Damage Detection for SMC Benchmark Problem: A Subspace-Based Approach

摘要: A full-scale bridge benchmark problem was issued by the Center of Structural Monitoring and Control at Harbin Institute Technology. The data used in this were collected an situ structural health monitoring system implemented into a cable-stayed before after damaged, which is very rare field. This will help to verify and/or make comparison condition assessment damage detection methods, are usually validated numerical simulation laboratory testing small-scale structures with assumed deterioration models artificial damage. With respect girder, one problems, using monitored field acceleration data, paper describes method, based on residual generated from subspace-based covariance-driven identification detect damage, give relative quantitative indexes. method applied both two parts given problem, then detailed discussions results reported paper.
