Abstract:
In this paper, reliability and sensitivity of steel and concrete piles for cohesive and cohesion less soils considered. For this purpose, Monte Carlo simulation, Importance Sampling and first order methods used for evaluating reliability index, moreover sensitivity of related limit states obtained by finite difference using Monte Carlo simulation and first order method. Comparison between results indicated that first order methods are appropriate for evaluation reliability of piles in cohesive soil and sensitivity analysis using theses method can be trusted as accurate results. But for sensitivity of piles in cohesion less soils, because of complexity and high nonlinearity of their limit states finite difference method must be used and also reliability result in first order methods is not accurate. Also it has been founded that cohesive factor and piles dimensions are sensitive parameter in cohesive soils, but for cohesion less soils, soil related parameters have a significant effect in reliability of piles.
