Abstract

In this paper, we attempt to estimate the bending-shear ratio of super high-rise buildings using the wave interferometry method. Firstly, some basic examinations on the relationship between the fundamental period and shear-wave travel time from the base to the top of buildings was performed. Then the bending-shear ratios of super high-rise buildings were estimated based on the ratios of the period of bending-shear vibration and the period of vibration only in shear mode. We found that, in the heterogeneous shear model, four times of the travel time from the base to the top is about 1.33 times of the fundamental period regardless of the number of stories. In the bending-shear models, the difference between four times of the travel time and the fundamental period becomes larger with the increasing number of stories. The bending-shear ratio of super high-rise buildings over 120 m can be estimated accurately.
