The acceleration of urbanization has led to a sharp rise in the number of super high-rise buildings in China.However,the issues related to the operation and maintenance of those buildings have become increasingly prominent.As a result,extensive attention to the service safety of super high-rise buildings have been paid.Summarizing and analyzing the theoretical methods and practical applications of identifying dynamic characteristic parameters of super high-rise buildings,the characteristics of super high-rise building structure monitoring technique,which were represented by the time domain,frequency domain,time-frequency domain and the new modal recognition method.Subsequently,the advantages and limitations of each monitoring method and system were compared.Simultaneously,the main issues in the current monitoring technique for super high-rise buildings were summed and development trends of monitoring methods were discussed.Eventually,the application of dynamic characteristic identification in the monitoring of super high-rise buildings was sorted out which would be expected to present a reference basis for improcing accurcy,effectiveness and reliability of dynamic characteristic identification for super high-rise buildings and provide reference to improving operation and maintenance levels for super high-rise buildings in China.
