Comparison of Analytical Approaches to Tall Building Structural Damage Identification Based on Measured Dynamic Characteristics

In the past two decades, there are many modal-based indices have been proposed for structural damage identification. In the present study, a modal of a 38-story building was tested on a shaking table to subject to four levels of earthquake, and the acceleration responses at nine floors of the structure are measured and used to construct five damage indices respectively. The experiment makes it possible to verify the applicability of vibrationbased identification methods in identifying structure damage without use of structural finite element model. Damage in the structure after experiencing different attacks is evaluated via five modal-based damage indices respectively .By comparing the solution of above indices, it is concluded that the five modal-based indices didnt have consistency in the identifying and localizing the seismic damage.
