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。
Based on CFD (computational fluid dynamics) method, the wind pressure characteristics of the cable dome structure at the opening were studied. Under the influence of different wind speeds and wind direction angles, a systematic study of the average wind pressure distribution of a single opening of a cable dome structure at different positions, and a plurality of different forms of opening at the same time on the bottom and top of the structure was conducted. Through the analysis of the simulation results, The distribution of average wind pressure coefficients of cable dome structures with different openings is obtained. The results show that the wind pressure characteristics of the open dome structure are closely related to the form, location and wind direction of the open hole. The research results provide a reliable theoretical reference for the wind-resistant design of the open-hole cable dome structure.
