Characteristic Analysis of the Response Mechanics of Asymmetric High-rise Buildings Subjected to Transverse Wind Loads Considering Second-order Vibration Patterns
The share of high-rise structures in China is growing as a response to the ordinary human wishes of today, such as high-rise accommodations and high-altitude enjoyment facilities. Because of the different traits of high-rise buildings, it is critical to find out about the load response and mechanical traits of high-rise buildings. In this paper, first of all, from the aerodynamic modeling experimental methods on the basis of three-dimensional wind-induced vibration of high-rise structures, high-rise buildings, the side-strain combination of the proposed simple and calculation formula, the basic characteristics of three-dimensional wind-induced vibration of a systematic study. The modal pushover evaluation technique is then used to analyze the elasticity and plasticity of the high-rise structure, and it is counseled that the higher-order vibration sample has a vital effect on the seismic resistance of the structure. Finally, a calculation principle of the mechanical response of high-rise construction subjected to transverse wind load thinking about the second-order vibration mode is given, and the outcomes exhibit that the Contribution of the second-order vibration mode to the dynamic displacement in the winding course of high-rise construction is inside 2%. However, the most Contribution to the acceleration response can attain 18%.
