Abstract: Systems and methods of determining a tension of an anchor embedded in a dam are described. A dynamic impulse response of the dam is empirically obtained in such that a portion of the empirical dynamic impulse response is dominated by a dynamic behavior of the anchor. Furthermore, a set of modeled impulse responses that map to a set of tension values for the anchor are obtained. Next, a closest matching modeled impulse response from the set of modeled impulse responses that is a closest match to the portion of the empirical dynamic impulse response that is dominated by the dynamic behavior of the anchor is determined. Finally, a tension value from the set of tension values is selected, which is the closest match to the portion of the dynamic impulse response dominated by the dynamic behavior of the anchor. As such, the tension value of the anchor can be determined.

Abstract: A significant number of rescue workers are killed or injured each year as they conduct searches within damaged or burning structures, unaware that the structure is unstable. The present invention provides a system and method for real-time detecting and monitoring structural instability that may lead to inevitable collapse of a structure. The system is capable of displaying data, including visual and/or audible signals, indicating structural instability. Additionally, the present invention is also directed to stability monitoring analysis processes for determining structural stability or instability.

Abstract: A significant number of rescue workers are killed or injured each year as they conduct searches within damaged or burning structures, unaware that the structure is in imminent danger of collapse. The present invention provides a system and method for detecting and monitoring structural damages which are irreversible and which lead to inevitable collapse of a building or structure. The system includes at least one accelerometer that is housed in a device that is mounted on an exterior surface outside the burn area, and within the reach of the rescue worker. The device communicates with a remote display that provides visual and/or audible signals to indicate imminent collapse of the structure. Additionally, the system includes collapse detecting analysis processes for determining the likelihood of collapse.
