| 摘 要： | 利用随机模拟风振分析方法对Kiewitt6—6型单层球面网壳和三向网格单层柱面网壳的风振性能进行了系统的参数分析，包括几何参数、气动参数、结构参数等，得出可供单层网壳结构抗风设计参考的风振系数。结果表明，单层网壳结构的风振系数分布较为均匀，大致为3．0。

| Abstract: | Systematic parameter analysis of wind-induced response of Kiewitt6-6 type single-layer spherical reticulate shells and three-way grid single-layer cylindrical reticulate shells structures have been performed with random simulation method in time domain,including geometric parameters,structural parameters and aerodynamic parameters.Moreover,the wind-induced vibration coefficient was obtained,which can be for the reference of the wind-resistance design of reticulated shell structures.The results indicate that the wind-induced vibration coefficient of these two kinds of structures is well-proportioned,which is approximately 3.0. |
