摘要
为了给体育场初步设计阶段选取风压系数提供参考,构造了马鞍形、平屋盖矩形、单侧看台月牙形和双侧看台月牙形4种典型体型体育场模型,并引用《欧洲张力薄膜结构设计指南》的罩棚标准化分区,采用计算流体力学(CFD)方法对4种典型体型体育场的风压系数和分布形式进行了系统研究,绘制了设计取值图供工程参考使用,并总结了各类体型体育场风荷载的规律.
In order to present reasonable roof wind load value for preliminary design of outdoor stadium,four typical shape stadiums were modeled in this paper which were saddle-shaped roof,rectangular roof,single-side roof and double-side roof.Roof regions were defined according to ＇European Design Guide for Tensile Surface Structures＇.Computational Fluid Dynamics（CFD） method was adopted to simulate wind loads acting on four kinds of typical shape stadiums.The features of the wind distribution were obtained,and the envelope map of each local area was also made to offer reference for wind load design.
