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 Buildings

该文根据风载及玻璃幕墙的变形特点，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。结果也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 characteristics of wind load and deformation of glass cladding, a simple and practical calculating formula for wind load of glass cladding is presented; the strict calculating formulas for wind induced response, wind induced vibration force and coefficient of glass cladding are established; according to the international popular Davenports wind spectrum, a convenient and practical calculating formula for wind induced vibration coefficient is given. These results can be applied to the claddings made of other materals,which provides convenience for engineering design.
