Pile integrity testing using low-strain tests such as the TDR (Transient Dynamic Response) method, is a rapid way of assessing the continuity and integrity of concrete piled foundations. The test measures: pile length, or depth to anomalies; pile head stiffness; pile shaft mobility, which is dependent on pile section and concrete properties
Thermal Integrity Profiling (TIP) is a non-destructive testing method used to evaluate the integrity of concrete foundations. It is standardized by ASTM D7949 - Standard Test Methods for Thermal Integrity Profiling of Concrete Deep Foundations. The testing method was first developed in the mid 1990s at the University of South Florida.
Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage. This method provides little indication of ...
Foundation integrity testing is the non-destructive testing of piled foundations.It was first used in the late 1960s, and has been developed over time by many companies. Three organizations supply a majority of the test equipment in use: CEBTP (Centre Expérimental de Recherches et d'Etudes du Bâtiment et des Travaux Publics) in Europe; Integrity Testing in Asia and Australia: and by GRL ...
Dynamic load testing takes a further step in analyzing the data and computing static capacity and resistance distribution. Dynamic pile monitoring takes advantage of the fact that, for driven piles, it is possible to compute the energy delivered to the pile, compression stresses at the pile top and toe and tension stresses along the shaft.
The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s. [1] On May 27, 1940, U.S. researcher Dr. Floyd Firestone of the University of Michigan applies for a U.S. invention patent for the first practical ultrasonic testing method.
