【摘要】 单层柱面正交异型网壳是一种新型的网壳形式。利用空间杆系有限元法 ,针对采用边桁架支撑的单层柱面正交异型网壳 ,进行内力计算 ,分析其在不同边界约束条件下的静力特性 ,并与采用拱形圈梁支撑下的网壳进行比较 ,为结构造型及工程设计提供依据。更多还原

【Abstract】 Cylindrical orthogonal single-layer lattice shell structures is a new type of space structures. Using finite element methd,this paper investigates the static behavior of cylindrical orthogonal single-layer lattice shell structures with fringe truss.In the analysis, different support conditions are considered, and the comparisons with that the lattice shell structure is supported directly on arch beam are presented. The results can serve as theoretic basis for engineering practice of this type structures.更多还原
