摘要
板锥柱面网壳是一种新型的空间结构形式 ,它是建立在板锥单元系和常规的双层柱面网壳基础上的一种结构。论文基于有限元法 ,针对两种不同支承情况进行结构分析计算 ,研究板锥柱面网壳结构在静荷载作用下的位移和内力分布规律 ,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。
Plate-cone cylindrical reticulated shell is a new type of space structures composed with plate-cone element and double layer cylindrical reticulated.For two different braces,displacements and internal forces of plate-cone cylindrical reticulated shell under dead loads is studied based on finite element analysis.The valuable results are got to instruct the application and engineering design of plate-cone cylindrical reticulated shell.
