| 摘 要： | 基于有限元法，以两纵边支承的板锥柱面网壳结构为研究对象，运用时程分析法分别计算板锥柱面网壳结构在水平地震和竖向地震作用下的地震响应，分析研究了板锥柱面网壳结构在动力作用下的位移和内力分布规律，结果表明，其竖向地震反应要大于其在水平向地震作用下的地震反应。同时分析了此结构在地震作用下的支座反力特点。在此基础之上，得出了一些有价值的结论，为板锥柱面网壳结构的应用和设计提供理论指导。

| Abstract: | Plate-cone cylindrical reticulated shell that is supported through two longitudinal edges is studied in this paper.Earthquake responses of plate-cone cylindrical reticulated shell in horizontal earthquake and in vertical earthquake are calculated based on finite element analysis and direct dynamic analysis.Rules of displacements and internal forces in dynamic action are achieved.It is indicated that earthquake responses in vertical earthquake are greater than those in horizontal earthquake.Features of reaction force are analyzed.The valuable results are got to instruct the application and engineering design of plate-cone cylindrical reticulated shell. |
