ABSTRACT |
The reliability assessment of the load carrying capacities of piles based on static approach with special consideration to steel as pile type in cohesive and cohesionless soils is reported in this paper. Uncertainties are common phenomena in engineering, therefore all the interrelated variables in the load carrying capacities are treated as random variables with assumed practical probability density functions. The concept of the First-Order Reliability Method (FORM) is a powerful tool for estimating nominal probability level of failure associated with uncertainties and it is the method invoked for the reliability estimations. From the results, it can be concluded that steel piling should be encouraged in cohesive and cohesionless soils; it is good to use steel piles in cohesionless soils.
Keywords: Probabilistic failure analysis, static pile capacity, steel piles, cohesive soils, cohesionless soils.
