| dc.description.abstract | The structural stability performance of shell structure is advanced. Corrugated shells are among the most unique shell structures available. These shells are shells of translation made up of a series of barrels shells with opposite Gaussian curvature connected edge to edge. The structural stability and performance of these types of shell structures in variable geometry and support condition must be precisely identified to build them. Many researchers have studied the structural performance of different shell structures. Studies on corrugated shell structures are few. The structural performance of a corrugated reinforced concrete shells with various curvatures and support position is the focus of this study. This research has been started by modeling individual barrels and corrugated multi-span shells by using SAP2000 software. The shells are analyzed by using SAP2000 software using various parameters. The result gain from SAP2000 is validated by using ANSYS software. Then the results of the SAP2000 analysis have been collated and graphically presented. Finally, the behavior and performance of the shell structures have been discussed based on the numerical results. According to the research shortening the span length and radius increases the stability of cylindrical shell structures, in addition, increasing the thickness and number of corrugations increases the global stiffness of corrugated shell structures. | |
