ECONOMICAL DESIGN OF A SINGLE SPAN LONG CYLINDRICAL SHELL ROOF WITH EDGE BEAM USING THE SCHORER THEORY

Cylindrical shell roofs are common types of shells used for the structures, which provide large free area without columns. In present work, a single span cylindrical shell (arc of a circle as directrix) with edge beam has been analysed and designed. The Schorer Theory which is extensively used for long shells has been used for the analysis. A program in C language has been developed to analyze the shell and to give the reinforcement details with edge beam and a solid diaphragm traverse. A simple iterative technique is used to get the economical geometry of the shell structure. Economical geometry of the shell with edge beam has been presented for one set of span, radius of the shell and depth of the edge beam which is taken as constants. The thickness, semi-central angle of the shell and width of the edge beam are treated as variable.
