摘要
通过数值模拟研究了某超高层建筑群风荷载特性及相互干扰效应。结果表明:不同风向角对建筑群体周围风场影响较大,在建筑角部及塔楼之间的空隙位置存在显著的加速现象。建筑风荷载及顺风向阻力系数受相邻建筑干扰明显,随着风向角的改变,建筑表面风荷载及整体受力特性都会发生相应变化,在实际设计中,应考虑建筑群体效应对设计风荷载的影响。
Through numerical simulation,the wind load characteristics and wind induced interference effect of high rise buildings are studied.The results show that the wind angle of different wind direction has great influence on the wind field around buildings,and there is a significant acceleration effect in the gap position between buildings.The wind force and the wind resistance coefficient of buildings are significantly disturbed by adjacent buildings.With the change of wind direction,the wind load and wind force characteristics of building will change accordingly. In the actual design,we should consider the influence of interference effect of high rise buildings on wind load.
