混凝土大跨度密肋式折板壳的结构形式与分类

Structural Form and Sort of Concrete Large-span Folded-plate Ribbed Shell

大跨度密肋式折板壳结构是一种新型的混凝土空间网格结构,它由密肋平板按一定规律相交组成,受力性能类似于壳体。通过对空间几何体的切割和组合,可以得到其丰富的造型,本文按外形特征对这种结构进行了分类,并介绍了结构的组成和支承形式,可为工程应用时结构的选型提供参考。

The large - span folded - plate ribbed shell is a sort of new type concrete spatial grid structure which is formed by ribbed slab, its mechanics behavior is similarly to concrete shell. The numerous form of this kind of structure is able to be gained by sundering or connecting geometric solid, this paper classify the fold -plate ribbed shell by structural form, as well as, ingredient and support measure is introduced, structural form can give some referrence to project design.
