Structural damage detection using real-time modal parameter identification algorithm

摘要: A new approach to conducting structural damage detection is described. The employs a real-time modal parameter identification algorithm implemented in digital-signal-processor-based data acquisition system. Because the extraction process conducted real time, capable of identifying changes properties attributable as soon they occur. Using and laboratory truss structure, it demonstrated experimentally that continuous, monitoring anomalies feasible. This capability will provide an early warning operator so proper measures can be taken before catastrophic failure occurs. results study using are presented along with description algorithm.
