公寓铝幕墙风荷载体型系数精细化分析

本文以北京冬奥运村公寓建设项目为工程背景,采用计算流体力学,基于大涡模拟对铝幕墙空腔装饰构件的风荷载体型系数进行研究．研究发现,在不同工况下,装饰构件法向风荷载体型系数整体大于切向风荷载体型系数,拐角区域的装饰构件会比平直区域的装饰构件受到更大的风压作用;建筑的风荷载体型系数的变化幅度会随着所在高度的增加而愈发明显．研究结论对该工程的幕墙设计及其连接件设计提供了精细化的荷载数据．

Refined Analysis of Wind Load Shape Coefficient of Aluminum Curtain Wall in Apartments

Taking the Beijing Winter Olympic Village apartment construction project as the engineering background, this paper studies the wind load shape coefficient of the cavity decoration components of the aluminum curtain wall using computational fluid dynamics and large eddy simulation. It is found that under different working conditions, the shape coefficient of normal wind load of decorative components is generally larger than that of tangential wind load, and the decorative components in the corner area will be subjected to greater wind pressure than those in the straight area. The variation of wind load shape coefficient of buildings will become more and more obvious with the increase of height. The results of this work provide refined load data for the curtain wall design and connector design of the project.
