Reliability Based Deep Foundation Design Using Texas Cone Penetrometer (TCP) Test

The goal of this study is to update Texas Department of Transportation (TxDOT) design guidance for deep foundations to reflect the reliability of the Texas Cone Penetration (TCP) based design method. The study will evaluate the performance of the TCP method and will include calibration of the resistance factors for load and resistance factor design (LRFD) design of axially loaded drilled shafts and driven piles designed using TCP data. These resistance factors will be established from a database of instrumented load test data obtained from Texas archive files and supplemented by load test data leveraged from neighboring states.
