| 摘 要： | 双拱大跨度网架屋盖结构由于体表为复杂曲面,其风荷载的确定不能仅参考我国建筑结构荷载规范中对风荷载的相关规定,风荷载的确定需要借助于其他手段。CFD数值模拟风洞是近年来发展起来的一种风荷载研究手段,基于ANSYS-CFX 12流体动力学软件,利用雷诺应力（RSM）湍流模型对一双拱大跨度屋盖结构上平均风载体型系数进行数值模...

| Abstract: | Due to the complexity of large span double-arched roof structure,Chinese load codes are not enough for the design.Other method should be used to ascertain the wind load on the roof structure.The distribution of wind pressure and wind environment on the roofs of large span double-arched structure were computed based on ANSYS-CFX12 software platform with Reynolds stress model(RSM).By the simulation,the unfavorable wind shape coefficient is obtained,which help the designer to enhance the key component for the safety of the serviceability performance when computing the wind load on the surface of a structure. |
