In the field of civil engineering, complex structures with interconnected bolts such as steel truss warehouses and bridges have significant merits including fire resistance, high strength and inexpensive erection etc. However, bolt-loosening faults frequently generate as well due to excessive vibration and impact loads. Therefore, a large number of frequency domain fault diagnosis methods based on nonlinear vibration TFs have been proposed and applied.
