Abstract
The structural roof is an integral part of the structure's envelope which is found in utmost houses and in other buildings. The structure is a series of trusses, beams and rafters that gives roofs a shape and that the structure roof is laid upon. For example, thin-walled dome structures have been used in building construction for many years because they are structurally efficient and use less material to enclose larger spans. They are used in a wide range of applications, including numerous historic and religious engineering projects. This study focuses on spherical shell optimization with different Radius of curvature to thickness ratios. The structural behavior of any shell structure depends on the self-weight, stress and displacement with thickness, span and rise being the major geometric parameters. Linear static analysis is carried out using Finite element software Ansys 18.1 for the form-finding of shells. The most efficient form based on the analysis is achieved by varying the geometric characterization.
