Interpretation of Instrumented Driven Steel Pipe Piles

This paper presents the results of a series of studies on the behavior of driven close-ended steel pipe piles. Extensive field explorations and geotechnical analyses have been carried out. Load tests were conducted, and strain gages and tell-tales were installed on tested piles. The behavior of the instrumented piles has been monitored for 14 months since pile driving. One emphasis of this paper is upon the magnitude and distribution of residual stress after pile driving and load testing. This paper also illustrates the setup of pile capacities after driving.
