摘要
弹性曲弯网壳结构不同于常规形式的空间网壳结构,具有特殊的建造方式.本文对这种特殊空间网壳结构的找形分析和承载设计过程进行了研究,对其设计中的材料选择条件、建造过程中的顶升找形特征以及承载计算中的杆件曲弯影响进行了深入的分析探讨.
Bent-up grid shell is one special form of spatial structures which is constructed by uncommon method. This paper studies form-finding mechanism and structural behavior under loading of the bent-up grid shell, and thoroughly discusses its design method with consideration of material characteristic, the erected process for shape finding and the initial bending imperfection effect on the ultimate strength of the structure.
