  • Method and apparatus for testing load-bearing capacity
    Patent number: 9499956
    Abstract: In an embodiment, a hydraulic jack is provided having a first portion and a second portion. The first portion attached to a first section of a structure and the second portion attached to a second section of the structure. When a pressurized fluid is forced between the first portion and the second portion, a load is transferred to the first section and the second section by the pressure of the fluid on the first portion and the second portion. The first section and the second section are forced apart by the load, thus creating or enlarging at least one void in the structure. The pressurized fluid fills or partially fills one or more of the at least one void, thereby increasing the surface area effectively normal to the direction of the load in contact with the pressurized fluid.
    Type: Grant
