Sažetak
This article provides an insight into the influence of the soil variability on the performance of a monopile type of wind turbine foundations subjected to long-term lateral cyclic loading. Stochastic simulation is performed based on a statistical model of the soil stiffness represented by the random field theory. Variability in soil stiffness is transformed by the numerical model of the pile- soil system in the uncertainties of resulting pile deflections and rotations. A statistical representation of the resulting pile rotations is used for the probabilistic assessment of the serviceability limit state. Cyclic soil behavior is taken into account by means of an elasto-plastic stiffness degradation model.
