The mesh size is important in analyzing the vault structures with the
finite element method. These structures which consist of curved surfaces need
to be divided into the appropriate number of finite elements to obtain reliable
results because the mesh size influences the accuracy of the results more than
those of isotropic structures. In this research, four different curvature types
such as circular, elliptical, parabolic, and cycloidal are considered. The material properties are assumed to be
isotropic and homogenous. In this
research, the finite element package program ANSYS is employed to analyse the
considered structures subjected to several static loadings. The effects of
transverse shear deformation are included by using the SHELL209 element. This
element is designed for the analysis of thin to moderately thick shell
structures. This element features eight nodes, each with six degrees of
freedom: translations along the x, y, and z axes, as well as rotations around
these axes. Results are obtained in terms of displacements, principal stresses,
Von-mises stresses, and strains. Clamped, pinned and roller supports are used to
define different boundary conditions.
