A concrete shell, also called “thin shell” concrete structure, is composed of a thin shell of concrete formed in such a way as to be self-supporting, often with no interior columns or exterior buttresses.The shells are most commonly flat plates and domes. Shells are constructed from concrete, profoundable due to the combination of filling and load carrying capacities. They are usually constructed of concrete reinforced with steel mesh (see shotcrete). Depending on the type of structural elements, vertical and horizontal construction joints are provided at different stages of construction.

Particularly, the production, placing, and curing of concrete must be under firm control. This article was most recently revised and updated by, https://www.britannica.com/technology/shell-structure-building-construction. The normal standards for the construction of concrete structures are, of course, absolutely necessary for shells. Pioneering thin-shell designers include Felix Candela and Pier Luigi Nervi. Premium Membership is now 50% off! Image Cortesia de Alexander Eisenschmidt. To build a satisfactory shell requires a detailed study of the methods of construction, well prepared plans, and good supervision. Large span concrete shell roofs are an ideal solution and is a result of a unique synthesis between architecture and structural engineering. Black Friday Sale! Folded PlatesPrismatic folded plates Non-prismatic folded plates Faceted folded plates 2. The construction of a reinforced concrete shell involves many problems, the design and construction of forms, reinforcement selection and placing, concrete materials and placing, and curing and decentering. Shell structure, in building construction, a thin, curved plate structure shaped to transmit applied forces by compressive, tensile, and shear stresses that act in the plane of the surface. Shell construction began in the 1920s; the shell emerged as a major long-span concrete structure after World War II. Construction joints in concrete are inevitable as we cannot finish the work at once. All of these problems must be understood in order to make the structure safe and economically feasible. 26/06 1 am.
