What can possible be dramatic about a foundation? Foundations perform a utilitarian function by transferring the loads collected by and originating withing the structure to the supporting soil and they do it quietly without fanfare. The following article is about thin shell foundations. The main advantage of these foundations are their capacity to distribute loads of considerable magnitude with low intensity of soil pressure, with an economy of materials and without introducing into the foundation structure excessive bending moments and shearing stresses. There are two main type of thin shell foundations. One is the hyperbolic paraboloid is a warped surface having these geometric characteristics: (1) a flat plane is warped by depressing two opposite corners and elevating the other opposite corners leaving the center fixed in its original position. (2) The edges of the figure continue to be straight lines but slope to conform to the elevations and depressions resulting from raising and lowering adjacent corners. (3) The genetrices of the curves are straight lines connecting opposite edges varying in slope as the elevation of the edges vary. (4) The resulting paraconcaves in an upward direction slide along paraconcaves in a downward direction. (5) If the shape is cut by a horizontal plane, the intersection will be hyperbolic. The quality which gives the hyperbolic paraboloid form its great structural strength is that the entire shape is made up of two sets of parabolic arches, each set normal to the other and each of the same shape but of opposite sign. This produces a situation in the structure in which all uniform loads generate forces in the shape which are always in equilibrium. The second main type is the hyperbolic paraboloid umbrella. The umbrella is formed by abutting four hyperbolic paraboloids in rectangular figure. All stresses to which it may be subject can be concentrated vertically at the point of intersection of the four hyperbolic paraboloids. These forces will consist of the compressive stresses resolved along the edge beams and directed vertically into the supporting column in accordance with their components and in conformity with the laws of statics. The magnitude of compressive forces in the edge beams forming the ribs of the umbrellas and tensile forces along the free edges of the umbrella can be computed very simply based upon uniform live and dead loads and the ratio of depth to length and breadth of the hyperbolic paraboloids by strict laws of statics.
