| 摘 要： | 风荷载是大跨度单层网壳结构设计的控制荷载,因结构体型复杂,结构表面的风压和风载体形系数难以确定。文中采用数值风洞技术研究复杂体型单层网壳结构的风压分布、风载体型系数,并利用有限元理论在时域上计算大跨度单层网壳的风振系数,为大跨度网壳结构的抗风设计提供了准则。

| Abstract: | The wind action is one of the most important loads acting on long-span space structure.However,it is rather difficult to get the relative wind pressure distribution on the structural surface with complicated shape.In this paper,the digital simulation technique is introduced to study the wind flow field around the spatial reticulated shell structures.The finite element method is used in the time domain to obtain the wind-induced vibration coefficients. |

| Keywords: | long-span spatial reticulated shell structures shape coefficient wind-induced vibration coefficients |
