Interpretation of Site-Specific Reliability Index for Piles Using Multiple Bidirectional Tests

What is it about?

A methodology for estimating the geometric reliability index of piles using the Osterberg cell testing is proposed. A dataset of load−displacement curves including 26 Osterberg cell-tested drilled shafts at the Los Angeles Memorial Coliseum site is used to illustrate the proposed method. Statistical analyses are performed on two-parametric power law curve-fitting regression variables. The bivariate normal and non-normal models are then used to predict the reliability index of these drilled shafts.
