    PLAXIS 2D Tutorial 10: Cyclic vertical capacity and stiffness of circular underwater footing

    Application PLAXIS 2D
    Version PLAXIS 2D
    Date created 01 November 2019
    Date modified 16 May 2022

    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.

    UDCAM-S: Cyclic accumulation tookl: Stress-strain curves for total load

    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.

    This exercise requires a PLAXIS 2D Advanced or PLAXIS 2D Ultimate license.

    The attached *.p2dxlog file contains all the commands to generate the model. With a Bentley Geotechnical SELECT Entitlement [GSE] licence, you can use the commands runner to open the *.p2dxlog file and to execute all commands in one go, see also this instruction.
