The bridge considered in this study is a 5-span (230m long span length) and, 464m-long concrete cable-stayed girder bridge, which foundation consists of drilled shafts (2500 mm diameter and 55m long) socketed in weathered rock. The Bayesian theory was implemented to update distributions of resistances followed by the resistance factors. The updated resistance factors reflecting the one not-failed proof load test result increased from 0.54 to 0.62 for target reliability index of 3.5. The LRFD method can result in cost savings and efficient shaft construction. Furthermore, the implementation of Bayesian theory reflecting the result of proof pile load test can contribute to more economical pile design by reducing margins of safety as compared to those by the non- Bayesian implemented LRFD.
