| dc.description.abstract | Architects and civil engineers are continuously looking for new and efficient methods to cover large spaces using the least materials and minimum number of columns. Thin concrete cylindrical shells can cover the roofs of various buildings efficiently and aesthetically. Common theories adopted for analysis of cylindrical shells interpret the design behavior in different ways. Nowadays it is easy to study shells to a desired level as tedious hand calculations are minimized due to the appearance of computer. As a result their behavior, specially their structural behavior, can be studied and designed by varying various parameters of the shell. The parameters, which are studied in this paper, are named as length, radius and thickness of the shell. Many researchers use computer knowledge to study shell behavior under variable parameters. This research was do ne using commercially available software MATLAB, Excel and manuals. Appropriate shell geometry, loading condition, material as well as other necessary parameters were assumed and selected according to manuals, codes and standards to achieve accuracy. The analysis was performed for stiffened and unstiffened single and multiple spans of reinforced concrete cylindrical shells with varying shell thickness, length, and radius keeping other things constant. Three models and seven trials with variable parameters for both single and multiple spans have been analyzed under dead and live load to obtain variable force, moment, stress and displacements. Results obtained from this research indicated that shells are varied in their behavior as one or two parameters changed as shown from Table (8-16) and Figure (5-7). Forces, moments, stresses and displacements were increased under increasing length and radius of shell. However, stresses and displacements were decreased and forces and moments were increased with increasing thickness of the shell. This study also adhere the reduction of internal effects when st iffeners were introduced and increasing depth edge beam were reduced the forces, moments, stresses and displacements. Finally it was also plotted a graph along longitudinal and circumferential directions of the shell for the purpose of reinforcement detailing. | en_US |
