PISA design model for monopiles for offshore wind turbines: Application to a stiff glacial clay till

Offshore wind turbines in shallow coastal waters are typically supported on monopile foundations. Although three-dimensional (3D) finite-element methods are available for the design of monopiles in this context, much of the routine design work is currently conducted using simplified one-dimensional (1D) models based on the p-y method. The p-y...

PISA design model for monopiles for offshore wind turbines: Application to a marine sand

This paper describes a one-dimensional (1D) computational model for the analysis and design of laterally loaded monopile foundations for offshore wind turbine applications. The model represents the monopile as an embedded beam and specially formulated functions, referred to as soil reaction curves, are employed to represent the various...

Uncertainties in Redesigning an Existing Quay Wall

A feasibility study was carried out on the redesigning of an existing quay wall of a core harbor in the Netherlands, which was more than 45 years old. The geotechnical behavior of the existing quay wall, especially because of its age, as a response to the maximum load change is undoubtedly the uncertain parameter here. The design and redesign...

Influence of Model Accuracy on Load and Resistance Factor Calibration of Steel Strip Walls

This study examines the load and resistance factor design calibration for the ultimate pullout limit state for steel strip reinforced soil walls (SSWs). The tensile loads and pullout capacities of reinforcement strips that were measured during full-scale tests are compared with predicted (nominal) values using analytical models recommended by...

Soil Probabilistic Slope Stability Analysis in Comparison with Limit State Design Method According to Eurocode 7

The paper contrasts results obtained by the partially factored limit state design method and a more advanced Random Finite Difference Method (RFDM) in a benchmark problem of slope stability analysis with random undrained shear strength parameter. Local Average Subdivision method was used to simulate a non-Gaussian random variable. The key...
