当超高层建筑的高度和间距都比较接近的时候,相互的干扰效应对结构的表面风荷载与结构的风致响应都会产生较大影响。基于刚性模型表面测压风洞试验,得到了双塔楼超高层建筑表面各测点的风压时程。在此基础上,通过数据处理,得到结构的三维动力风荷载模型,进而分别采用频域法进行结构动力响应分析。最后,通过分析结构表面风荷载与风致响应,研究了塔楼之间的干扰对结构风荷载的影响以及对结构风致响应的影响,结果表明:当双塔连线与来流方向平行时,三维风荷载和风致响应都会明显增大,干扰效应影响十分明显。
When the height and spacing of super high-rise buildings are relatively close, mutual interference effects have a great influence on the wind load on the structure and the wind-induced response of the structure. Based on the rigid model surface wind pressure test, the wind pressure time history of each measuring point on the surface of double-tower high-rise building was obtained. On this basis, through the data processing, the three-dimensional dynamic wind load model of the structure is obtained, and then the dynamic response of the structure is analyzed by using the frequency domain method respectively. Finally, by analyzing the wind load and wind-induced response on the surface of the structure, the influence of the disturbance between the tower on the wind load and the wind-induced response is studied. The results show that when the connection between the two towers is parallel to the flow direction, Load and wind response will be significantly increased, the interference effect is very obvious.
