Paraboloid Shell As Footing

Abstract

A simplified method for the design of paraboloid shell footing base on the displacement of the shell's crown where the column axial load is transferred to the footing has been developed. A case study was presented to demonstrate the use of the proposed method and to illustrate its capabilities. The results of the proposed method confirm the ability of the shell model in determining accurate and practical results for the design of paraboloid shell footing. Base on the analytical results of this paper the paraboloid shell is more economical than the conventional flat footing on poor subsoil, and very competitive with other shell footings.
