中文摘要：

基于CFD（计算流体动力学）方法研究开洞口索穹顶结构的风压特性。在不同风速和风向角作用下,对索穹顶结构在不同位置上单一开洞、以及结构底面、顶部同时开多个不同形式洞口的平均风压分布进行了系统研究,通过对模拟结果的分析,得到了不同开洞形式的索穹顶结构的平均风压系数分布规律。结果表明,开洞穹顶结构的风压特性与开洞形式、位置和风向等有着重要关联。研究成果为开洞索穹顶结构的抗风设计提供了可靠的理论参考。

英文摘要：

Wind pressure characteristics of dome structures with openings are studied by CFD（computational fluid dynamics）method.For different wind velocities and wind directions,mean wind pressure distributions are systematically studied for dome structures with a single opening and multiple opening on different locations.Mean wind pressure distribution principles are obtained for dome structures with different opening forms.The results show that wind pressure characteristics of dome structures are closely correlated to opening forms,locations and wind directions.The study results provide reliable theoretical basis for the wind resisting design of dome structures with openings.
