本文在总结结构风振试验研究的基础上,提出了高层建筑的迎风面、背风面与二侧面的动扭矩是统计独立的假定及相应的计算参数和计算方法。计算实例表明,高层建筑在风荷载作用下的扭转振动是不可忽视的。
On the basis of summarizing the structural wind-induced vibration test, this paper proposes that the dynamic torque on the windward surface, the leeward surface and the two sides of the high-rise building is a statistically independent assumption and the corresponding calculation parameters and calculation methods. The calculation example shows that the torsional vibration of high-rise buildings under wind load can not be ignored.
