摘要
系统详尽地介绍了折板网壳的基本造型、结构形式和支承方式 ,并对设计、施工中需注意的要点做了说明。针对四边形正交正放四角锥折板网壳进行了自振特性计算 ,并进行了参数分析 ,研究了当结构厚度、屋面坡度以及支承方式等发生变化后对这种结构动力性能的影响 。
Hy\|rib pyramid lattice shell synthesizes the merits both of spatial truss and lattice shell,so it will be widely applied in practical projects.The configuration and geometric composition of hy\|rib pyramid lattice shell are introduced. Moreover,the dynamic properties are analyzed considering the influence of the different thickness or degree of shell,different support structure.Some valuable conclusions are obtained,which can provide a reference to civil engineering.
