| 摘 要： | 在我国高层建筑建筑规范中关于风荷载计算中有一振型函数表达式Φ_z=tan(π(Z/H)~(0.7)/4),这一公式在计算风荷载中被广泛采用。作者在对金茂大厦风振位移的观测和研究中,发现该公式与实际观测的结果不符。本研究给出金茂大厦这样的超高层建筑物的实测振型函数表达式:给出与建筑规范不同的风荷载振型函数,供建筑界参考;积累超高层建筑风振振型函数样本,以便在规范中给出符合实际振型函数的表达式,提高风荷载计算精度,设计出既经济又抗强风的超高层建筑。 |

| Abstract: | The mode function expression for computation the wind load of skyscraper in domestic ar- chitecture criterion, φx=tan（π（Z/H）^0.7/4）, is widely used. In the observation and study on the wind oscillation and displacement of Jinmao skyscraper, however, the authors found se- vere unconformity between the observation and computation based on this expression. In this paper, the actual mode function expression for skyscraper like Jinmao is presented. It pro- vides a mode function of skyscraper under wind load differing from the architecture criterion for the reference of architectonics and also accumulates more examples of mode function of wind oscillation of skyscrapers, in order to modifying the computation expression of wind os- cillation of skyscraper in architecture criterion, getting more precise response of wind load computation, and finally scheming out more economic and anti-strong-wind skyscrapers. |
