| 摘 要： | 风荷载在大跨度屋盖结构设计中常常起主要甚至决定性作用,这使得该类结构的风荷载及风致动力响应研究日益受到关注与重视。利用随机模拟时程分析方法对三向网格单层柱面网壳结构的风振性能进行了系统的参数分析,探讨了几何参数、气动参数、结构参数等因素对结构风振响应规律的影响,并在此基础上给出了可供单层柱面网壳结构抗风设计参考的风振系数。

| Abstract: | Wind load is always the major or even the decisive load applied to long-span spatial structures, so much more attention is paid to dynamic response of reticulated shell structures under wind load. Systematic parameter analysis of windinduced response of three-way grid single-layer cylindrical reticulated shell structures has been performed with random simulation method in time domain, including geometric parameters, structural parameters and aerodynamic parameters. Moreover, the wind-induced vibration coefficient is obtained, which may be a reference for the wind-resistance design of reticulated shell structures. |
