内容記述 Shells and spatial structures are adopted for construction of large span structures in which a large space is realized without columns as the structural components. In those cases, the structures are expected to resist against various design loads mainly through their extremely strong capability which can be acquired through in-plane or membrane stress resultants and this is just the reason by which they themselves stand for external loads without columns as their structural components in the large span structures. Up to this time, shells and spatial structures have been frequently adopted as a structure which can realize large span constructions, where, however, purely geometrical shapes like spheres, cylinders and their parts have been adopted as their structural forms. It can be said relatively easy to handle purely geometrical shapes from the view-point of both structural analysis and construction design, where, however, we have to handle bending stress resultants which are inevitably accompanied with especially in the vicinity of their supporting boundaries.
