Recent Development of Load and Resistance Factor Design (LRFD) for Driven Piles on Soft Rock
A study was recently completed to evaluate the performances of fifteen steel H-piles driven on soft rocks. The results showed that static analysis methods provided inconsistent geotechnical resistance estimations of piles driven on soft rock. DRIVEN method provided the most accurate estimation with the resistance bias of 1.369 and coefficient of variation of 0.80. Wave Equation Analysis Program (WEAP) tended to slightly overestimate the total pile resistance and shaft resistance but underestimate the end bearing. For the end of driving condition, the resistance bias and coefficient of variation for WEAP were determined as 0.988 and 0.294, respectively. The results revealed that almost all piles satisfied the load and resistance factor design (LRFD) strength limit state when pile driving analyzer (PDA) with subsequent signal matching analyses using CAse Pile Wave Analysis Program (CAPWAP) was considered as the construction control and 24-hour restrike tests were performed. Although conclusions were drawn based on Wyoming data and practices, they can be adopted by other agencies.
