Evaluation of Resistance Bias Factors for Load and Resistance Factor Design of Driven Steel Pipe Piles
Resistance bias factors for the two static bearing capacity analysis methods of driven steel pipe piles adopted in the Korean Design Standards for Structure Foundations were evaluated as part of study to develop LRFD codes for foundation structures in South Korea. Of the 2,227 static load test data on driven steel pipe piles collected from all around the country, only 43 were found to be useful for this study. These load test piles were sorted into two cases: pile tip in soil case and pile tip in rock case. Pile bearing capacities were measured from the load-displacement curves by six different failure criteria, and Davisson's criterion was found to be most reliable. Statistical analysis of the resistance bias factors was performed, and the results show a significantly high degree of variation in the resistance bias factors.
