高层建筑玻璃幕墙的风压和风振计算

The Wind Pressure and Calculation of Wind-Induced Vibration for Glass Cladding of Tall Building

本文根据风载及玻璃幕墙变形特点，探讨了简便、实用的玻璃幕墙风载计算公式；用板的随机振动理论，建立了玻璃幕墙风振响应、风振力、风振系数的严密计算公式；针对国际流行的Ｄａｖｅｎｐｏｒｔ风谱，给出了简便、实用的风振系数表达式。本文结果可适用于其它材料的幕墙，为工程设计提供了方便。

In this paper, according to the characterisitics of wind load and deformation of glass cladding,the handy and practical calculating formula for wind load of glass cladding is inquired;the strict calculating formulas for wind-induced vibration force and coefficient of glass cladding are established; according to the international-popular Davenport's wind spectrum,the handy and practical calculating formula for wind-induced vibration coefficient is given.These results can be applied to the claddings made of other materials and provide convenicence for engineering design.
