The most popular types of thin-shell structures are: Concrete shell structures, often cast as a monolithic dome or stressed ribbon bridge or saddle roof; Lattice shell structures, also called gridshell structures, often in the form of a geodesic dome or a hyperboloid structure; Membrane structures, which include fabric structures and other ...
The spectacular simplification of membrane theory makes possible the examination of a wide variety of shapes and supports, in particular, tanks and shell roofs. There are heavy penalties paid for this simplification, and such inadequacies are apparent through critical inspection, remaining within the theory, of solutions.
A thin shell is defined as a shell with a thickness which is relatively small compared to its other dimensions and in which deformations are not large compared to thickness. Wikimedia Commons has media related to Thin-shell structures .
A concrete shell, also commonly called thin shell concrete structure, is a structure composed of a relatively thin shell of concrete, usually with no interior columns or exterior buttresses. The shells are most commonly monolithic domes , but may also take the form of hyperbolic paraboloids , ellipsoids , cylindrical sections, or some ...
The world's first membrane roof and lattice steel shell in the Shukhov Rotunda, Nizhny Novgorod, All-Russia exhibition, 1895 Geodesic shell of Nagoya Dome by Takenaka Corporation, Nagoya, Japan, 1997. Shell of Kresge Auditorium by Eero Saarinen, MIT, Cambridge, Massachusetts, 1953.
Stress resultants are simplified representations of the stress state in structural elements such as beams, plates, or shells. [1] The geometry of typical structural elements allows the internal stress state to be simplified because of the existence of a "thickness'" direction in which the size of the element is much smaller than in other directions.
Unlike a vesicle or a cell membrane in which the lipid bilayer is rolled into an enclosed shell, a supported bilayer is a planar structure sitting on a solid support. Because of this, only the upper face of the bilayer is exposed to free solution. This layout has advantages and drawbacks related to the study of lipid bilayers.
Shukhov designed eight tensile structures and thin-shell structures exhibition pavilions for the Nizhny Novgorod Fair of 1896, covering the area of 27,000 square meters. A more recent large-scale use of a membrane-covered tensile structure is the Sidney Myer Music Bowl, constructed in 1958.
