Parametric study involving foundation parameters and shell geometry is carried out for nonlinear static behavior of an orthotropic shallow spherical shell on a Kerr foundation. Study shows that the deflection reduces if the shell curvature or the foundation parameters of the shear layer and the lower spring layer are increased. Shells with immovable edges are found to be more prone and vulnerable to changes in various parameters than those with movable edges.
