Structural Analysis of Concrete Spherical Shells

Studying landmark shells of the past can help engineers in designing efficient thin shell concrete structures. This paper presents structural analyses and the optimization study of several notable concrete spherical shells around the world. In structural optimization of these shells an attempt is made to reduce overall tensile stress, deflection and reinforcement to the system while changing the limits of the structure’s shape. The finite element analysis using Sofistik software shows that a distributed concrete thickness reduces shell stresses, deflections and reinforcements.
