Research Progress on Dynamic Characteristic Monitoring Methods of Super High-Rise Buildings

: 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.
