Soil-Structure Interaction for a Tension Pile Pulled with Strand
This is a unique tension pile where the pull is at a point, a certain distance below the top of the pile. The pull is transferred by a cable consisting of high tensile strands. The HDPE duct of the cable prevents bond between the strands and pile concrete in upper portion. While soil friction on the pile will act downwards on the whole length, there is tension in the bottom portion of pile, there will be compression at the top portion. This fact came to light while test loading this pile. Also, micro-strains in the pile concrete was measured as a routine. The resulting stress pattern in the pile is analysed in the paper.
