Abstract

This chapter introduces a novel OS@DF TF-based method for diagnosing bolt-loosening faults in grid-type structures, such as steel truss bridges and roofs. The method overcomes the limitations of existing fault diagnosis techniques by decomposing complex structures into simpler T-type substructures and analyzing them individually. A nonlinear T-type MDOF model is developed to simulate potential faults as nonlinear connecting elements, and harmonic excitation loads are used to derive novel and local nonlinear features. A sensitive fault indicator based on the Euclidean distance measurement is defined, allowing for precise fault detection. The method's effectiveness is demonstrated through comparative studies on a lab bolted grid-type structure, showcasing its superiority over existing methods based on general TFs and NOFRF TFs. The chapter provides detailed theoretical analysis and experimental verification, making it a valuable resource for professionals seeking advanced fault diagnosis techniques in structural engineering.
