Abstract

Field measurement of a high-rise building in Wenzhou has been taken during Typhoon HAIKUI and TRAMI respectively, and the acceleration data of the 25th layer and the elevator stopped at the 25th layer are obtained. Meanwhile, the time domain and frequency domain characteristics of the structure and elevator have been analyzed by MATLAB software programming. Results show that, the maximum acceleration of elevator and structure during typhoon increased with the increase of average wind speed. The wind-induced vibration of structure has transmitted to the elevator, and the overall elevator vibration response is performed by the amplification of the structure vibration response when the elevator inherent frequency close to the first few structure natural frequency. Within 10 minutes, the elevator maximum acceleration is about 1~1.78 times larger than that of the layer. Furthermore, the simplified calculation method for calculating the elevator horizontal vibration response has been put forward based on the high-rise building field measured data, which is expected to provide a reference for the elevator safety design and calculation.
