  • Pile cap
    Patent number: 5531544
    Abstract: A pile cap of homogeneous material is disclosed that includes a top member part having a relatively large top area and a base member part having a correspondingly smaller bottom area. The sides of at least the bottom member part are thereby tapered. The bottom area preferably includes a recess for accommodating the top of a cylindrical pile. The shape distributes even an unbalanced load having an off-center moment of force to the top of the pile without creating potentially damaging shear stresses along the sides of the pile cap.
