This tutorial illustrates how to calculate the vertical bearing capacity and vertical stiffness of a circular stiff underwater footing (e.g. one of the footings of a jacket structure) exposed to cyclic loading during a storm. The storm is idealised by a distribution of load parcels with different magnitude. The cyclic accumulation tool is used to obtain soil parameters for the UDCAM-S model. The example considers a circular concrete footing with a radius of 11 m, placed on an over-consolidated clay layer.
Objectives:
- Obtain the UDCAM-S model input parameters by running the cyclic accumulation procedure, determining the stress-strain curves and optimizing the material model parameters.
- Calculate the total cyclic vertical bearing capacity.
- Calculate the vertical stiffness accounting for cyclic loading for both the total and the cyclic component.
