In view of the health inspection of tower crane, the paper puts forward an ARX model to detect the status of the tower crane structure which uses the node displacements of tower crane below standard section as input and the up standard section of the node displacements as the output. Combining with statistical recognition technology the states detection of the structure are detected. First, the paper establishes a counterpart finite element model based on the laboratory existing mini tower cranes to obtain the displacement signals of tower crane nodes in intact and damaged states with excitation load. Then it chooses a better identified ARX model to define the damage characteristic parameter. Finally it judges the dynamic response of the good state as a reference to analyze the differences between the response signals of damage status and normal structures, so as to complete the diagnose with the method of statistical analysis. The method shows a high ability of damage identification.
