风荷载是结构抗风设计中的主要荷载,而现场实测、风洞试验、数值模拟是获取风荷载数据的主要方法。文章介绍了作用于结构上的大气边界层内风的特性、风荷载的特点以及风荷载的研究方法,讨论了在数值模拟中引入湍流模型的必要性,指出了目前计算流体动力学在结构风荷载计算中的进展并对今后的研究方向进行了展望。
Wind load is the main load in wind-resistant design of structures, and field measurement, wind tunnel test and numerical simulation are the main methods to obtain wind load data. This paper introduces the characteristics of the wind, the characteristics of wind load and the wind load acting on the structural atmospheric boundary layer. The necessity of introducing turbulence model in numerical simulation is discussed. The current computational fluid dynamics The progress in load calculation and the prospect of future research.
