Integrity Evaluation of Driven Concrete Piles Utilizing Embedded Data Collectors
Donald T. Robertson, Kurt Hecht, Michael K. Muchard
This paper presents case histories of driven concrete pile damage detected with dynamic testing methods utilizing strain gages and accelerometers embedded in the pile at the prestressing yard during pile construction. Data from the embedded instrumentation is compared with data taken with external bolt on instrumentation and other test methods such as low strain testing on the same pile. In the most severe cases, the piles were extracted revealing and corroborating the embedded data collector res.
