The following is an account of some of the more common types of shells used in foundations (Kurian, 2006): hyperbolic paraboloidal shells, conical shells, inverted dome, elliptic paraboloid, cylindrical shells, pyramidal sell, spherical shells, and triangular shell footing for load bearing wall.
The power intercepted by the aperture as a function of its diameter can be calculated using the mean concentration ratio of the paraboloidal concentrator and the normal beam insolation.
