The appropriate treatment of the building shape at its upper part may also reduce the across-wind loads effectively.
上部外形的适当处理,也可能有效降低高层建筑的横风向等效风荷载。
The results show that the calculation method of static equivalent wind loads is suited to along-wind force, but is in some theoretical error to across-wind force.
结果分析指出:提出的求沿高层建筑高度分布的等效静态风荷载的方法适用于顺风向风力,应用于横风向风力有理论误差。
What's more, the mechanism and calculation method of across-wind vibration of high-rise structure is expounded. The vortex-excited resonance response of the tower is calculate.
