As a part of study to develop LRFD(Load and Resistance Factor Design) codes for foundation structures in GwangYang region, reliability analyses for driven steel pipe piles are performed and target reliability indices are selected carefully. The 16 data sets of static load tests and soil property tests conducted in the whole domestic area were collected and analyzed to determine the representative bearing capacities of the piles. The static bearing capacity formula and the Meyerhof method using N values are applied to calculate the expected design bearing capacity of the piles. The resistance bias factors were evaluated for the two static design methods by comparing the representative bearing capacities with the design values. Reliability analyed methods : First Order Reliability Method(FOSM), and Monte Carlo Simulation(MCS) method using resistance bias factor statistics.
