| 20110203383 | Method to determine percentage of damage to structure from single or multiple forces - The present invention is directed at providing a numerical analysis method to determine the damage sustained on a structure based upon the physical dimensions of a the structure, the structure's design wind speed and the forces applied during an event such as a hurricane or man made event. The method includes the steps of creating a timeline by which event forces can be plotted and compared to an ultimate load of the structure, individual loads placed upon the structure as well as a sum of the individual loads placed upon the structure. By using this method, the user is able to identify the time at which the ultimate load of the structure was exceeded and the maximum individual and total loads occurred. The method further identifies the time when the structural failure likely initiated and the time by which the structural failure was likely complete. The method further provides a determination of the percentage individual load at the time the ultimate load is breeched as well as a time step of forces applied to the structure throughout the course of the event. | 08-25-2011 |

| 20130247679 | METHOD AND APPARATUS FOR TESTING LOAD-BEARING CAPACITY - 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. | 09-26-2013 |

| 20140352449 | HIGH STRAIN DYNAMIC LOAD TESTING PROCEDURE - A method is provided for using low-overhead equipment to perform a dynamic load test on pipe piles of a deep pile foundation for an existing building. The existing building is lifted to a predetermined elevation above grade and cribbing stacks are positioned to support the existing building at the predetermined elevation above grade. The cribbing stacks are spaced from each other enabling low-overhead equipment to maneuver underneath the elevated building to drill drive pipe piles and to position a drop weight used for dynamic load testing the driven pipe piles. Grout is pumped under pressure into the pipe piles continuously during the drill driving of the pipe piles so that grout exits through a grout port to mix with disturbed soil about the pipe pile to encase the pipe pile in a grout-soil mixture. Sensors are attached to the pipe pile being tested. The sensors provide information regarding the pipe pile impacted by the drop weight. Bearing capacity and other pipe pile characteristics that indicate whether the pipe pile tested is acceptable are determined from the information provided by the sensors. | 12-04-2014 |
