Abstract:"This project focused on instrumentation analysis of one Smart Structures Incorporated, EDC pile. In general, the EDC pile is a pre-stressed 18" x 18" concrete pile that has been outfitted with embedded strain gages and accelerometers at six locations along the pile's neutral axis. The purpose for these sensors is to provided the engineer with improved bearing capacity and pile stress estimates each time the pile is struck by the driving hammer. The primary objective of this project was to compare the data collected from these transducers with externally mounted sensors (accelerometers and strain gages) via two complementary and independed data acquisition systems"--P. 1.
