| 摘 要： | 网壳结构的大空间曲面形状特点使得其在台风作用下的风振响应比较复杂,为了克服尺寸效应的影响,得到网壳结构表面风荷载分布规律,在计算流体力学(CFD)和FLUENT技术的基础上,利用常规湍流强度、田浦湍流强度以及石沅湍流强度的计算方法,对某组合网壳结构进行了台风作用下风场的数值模拟,通过分析其表面风荷载分布特性和不同风向攻角作用下组合网壳结构的表面风荷载,确定了组合网壳结构的风压分布规律、表面风压系数分布,最后得到网壳结构的风敏感部位,可以为工程前期抗风设计提供参考。

| Abstract: | The features of large space and reticulated shell surface shape make the vibration response of latticed shell under the action of the typhoon wind be more complicated.In order to overcome the influence of size effect and get the load distribution rule of surface wind of latticed shell,based on computational fluid dynamics and Fluent,by using the calculation methods of conventional turbulence intensity,Tianpu turbulence intensity and Shiyuan turbulence intensity,the numerical simulation of a latticed shell under the action of the typhoon is carried out,through analyzing the distribution characteristics of the surface wind load and under the action of different direction angle of wind attack combination the surface wind load of the reticulated shell,it was determined the rule of the measured wind pressure distributions,wind pressure distribution coefficient of the combination latticed shell structure.Finally the parts of dome structures,which are sensitive to the wind are got,which can provide a reference for the design of wind engineering. |
