摘　　要：基于风洞试验,对某非等高连体双塔高层建筑的风致效应特性进行了研究,得到了各塔楼的平均风压分布及测点的风压时程。然后,对该高层结构的风荷载及其风致动力响应进行了研究,为该类双塔结构抗风设计提供了设计依据。结果表明,风向角、结构高度与重现期风速对结构表面风压分布与动力响应的影响较大。双塔之间的相互影响导致临近表面风场发生变化,从而引起风压发生显著变化。1^(#)塔楼结构的风致动力响应最大值满足中国相关规范的要求。Based on the wind tunnel experiment,the wind-induced effect of an unequal height twin tower high-rise building was investigated.The average wind pressure distribution of each tower and the wind pressure time history of the measuring points were obtained.Then,the wind load and wind-induced dynamic response of the high-rise structure were investigated to provide the basis for wind resistance design of this type of twin tower structure.The results show that the three key parameters of wind direction angle,structure height and wind speed for recurrence intervals have great influence on the wind pressure distribution and dynamic response of the structure surface.Due to the interaction of the twin towers,the wind field on the adjacent surface changes,resulting in significant changes in wind pressure.The maximum wind-induced dynamic response of 1^(#)tower structure meets the requirements of chinese relevant codes.
