Pile cap

DETAILED DESCRIPTION The current invention was designed to reduce the destructive effects of the shear stress on a pile cap and PATENT to increase the resistance against the rotational moment produced by the unequal distribution of forces on such a pile cap.
The inventive structure comprises a pile cap having two member parts, an upper member part with a top surface area and a base member part with a bottom surface area, the bottom surface area always being less than the top surface area.
Both member parts together comprise one homogenous structure.
At least the base member part has tapered sides.
The tapering of the sides of the structure reduces the destructive effect of shear stress.
The sides of the upper member part can either be tapered or vertical.
The base member part preferably also has a recessed bottom that is adaptable for placement on top of the piling.
This recess provides added resistance to that provided by an inverse, homogeneous frustum against an off-center moment from the unequal distribution of forces applied to the pile cap during use.
The shape of the top surface area of the upper member part and the bottom surface area of the base can vary.
Such shapes can be, for example, rectangular, square, circular, or elliptical.
