A Case Study of LRFD Implementation for Static Bearing Capacity of Driven Steel Pipe Piles in Korea

摘要

Resistance factors for static bearing capacity of driven steel pipe piles were calibrated in the framework of reliability theory. In order for the verification of resistance factors and the implementation of the LRFD, a case study on an actual bridge foundation designs using both the ASD and the LRFD methods is comprehensively accomplished. Detailed analysis showed that both of the design concepts gave the design bearing capacities equal to or more than the design loads. The LRFD method, however, could provide the quantitative provability of failure of the pile foundation, whereas the ASD method showed nominal level of safety.
