(中國電子工程設計院深圳市電子院設計有限公司，深圳 518031)[摘要] 對空中華西村超高層結構的風振舒適度進行研究，首先根據(jù)規(guī)范提供的計算公式，對整體結構中外圍單個塔體進行了風振舒適度驗算，結果滿足規(guī)范要求。在此基礎上進一步對整體結構進行了風振響應分析。由于整體結構比較復雜，規(guī)范方法不再適用，因此工程利用風洞實驗獲得復雜不規(guī)則建筑物表面的風壓時程數(shù)據(jù)，采用數(shù)值模擬的辦法分析了高層建筑在風荷載下的結構動態(tài)響應，獲得了整體結構位移、速度以及加速度時程等重要數(shù)據(jù)。方法為體型復雜、規(guī)范方法不適用情況下的高層建筑風振舒適度驗算提供了準確而全面的判斷依據(jù)。

( China Electronics Engineering Design Institute, Shenzhen Electronic Design Institute Co., Ltd., Shenzhen 518031, China)Abstract: To analyze the wind-induced vibration of Kongzhong Huaxicun, the simple calculation of the single tower among the total four towers in the project is accomplished with the formula provided by the design code and the results meet the demand of the code. Because the whole structure of the building is very complicated and traditional methods do not work, a new method is adopted. The structure's dynamic response under the wind load obtained in the wind tunnel test is simulated with ABAQUS and then the displacement, velocity and acceleration information are obtained. The analysis of the comfort degree of the complicated shaped structure under wind load could be accomplished successfully with this method. This method is of great importance to the structure design of skyscraper.
