#multiple cylindrical shells

The shell structure consists of a thin reinforced concrete shell without the use of internal columns to create an internal opening., parabolic or spherical cross section. On the other hand, warehouses and playgrounds are conventional concrete frame structures, on the other hand, they can be difficult to design as the exact shape required for the stability of the structure depends on the material used, the dimensions of the enclosure, external or internal loads and other chamfers.. .. Thus, by changing the shell parameter, the performance of the shell will also change. The main goal of this work is to parametrically analyze different designs of cylindrical shells of different lengths in order to analyze two different lengths of taken cylindrical shells, and then change two parameters, first the radius and then the thickness, based on the radii. and the difference in thickness for the same width, length and material of the frame, we will evaluate the behavior of the frame for different models. 

The shell structures are composed of a thin shell made of reinforced concrete without the use of interior columns giving an open on the inside. Most general shells used in manufacturing industries are flat plates and domes but different shapes like cylindrical, parabolic or spherical section may also used. Storage facilities and Games arena buildings are common concrete shell structures. On the other hand, they can be complicated to design, as the exact shape necessary for stability of structure depends on the material used, the size of the shell, exterior or interior loading, and other oblique. So by varying the parameter of the shell, performance of the shell is also varying. Main objective of this paper is parametric analysis of the various cylindrical shell structures with different lengths. For analysis we took two different lengths of cylindrical shell and then, two parameters have been vary first one is radius and second is thickness, on the basis of different radius and thickness for same chord width, length, and material of shell we will evaluate the behaviour of shell for different models.
