The wind-induced vibration comfort analysis of wuhan international securities mansion

Abstract

The chapter analyzes the stochastic wind-induced vibration response of the 281m tall Wuhan International Securities Mansion in Wuhan, China, under turbulent wind. The analysis is performed in the frequency domain by means of a stochastic vibration procedure, including in the general-use finite element software ANSYS. The wind-induced displacement, velocity, and acceleration responses under along and across turbulent wind are obtained in the chapter. The wind-induced vibration acceleration responses based on the stochastic vibration analysis, and the current load and structural code for the design of building structures in China are computed and compared in the chapter. The comfortable demand subjected to the stochastic wind-induced vibration is checked. The studies indicate that the across-wind response is larger than the along-wind one, and the design requirement of human comfort for the sightseeing hall of the building is not satisfied. These results provide important information for the wind-induced vibration analysis of super tall buildings.
