Design and Analysis of Reinforced Concrete Shells

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 flat plates and domes, but may also take the form of ellipsoids or cylindrical sections, or some combination thereof. A structural design of the thin shelled concrete structure will be computed using geometrical shape equations. Matrix methods offer an elegant and systematic means of formulating complex problems of structural analysis. Shells structures can be analysed using membrane theory and bending theory. The analysis and design of shell structures of circular cylinder shape have been done using D.K-J theory and Schorer theory D-K-J Theory has been used for design of short shell with edge beam and Schorer theory has been used for the analysis of long shell with edge beam. Reinforcement details have been provided based on calculations of stress resultants at different sections of the shell.
