Abstract

Shells are thin structures that have high load carrying capacity; this advantage can be used to transmit heavy super structural loads to weak soil. Shallow spherical dome with variable thickness resting on Pasternak foundation is studied considering external vertical pressure. The governing differential equation is derived neglecting the strain energy of second strain invariant of middle surface (Berger's approach). Analytical solution of the governing differential equation is presented. Parametric study is executed considering thickness nonlinearity constant and Pasternak foundation constants.
