Analysing the sinking resistance of piles using allowable bearing pressures

Version 2025.d includes the option to select the calculation mode of the pile sinking resistance in the module "Piles I: Calculation of sinking load":

  • By indicating the "Geotechnical parameters" (available since previous version -2025.c)

  • By indicating the "Allowable bearing pressures"(implemented in version 2025.d)
    This option is used to calculate the pile considering the allowable bearing pressures defined in the geotechnical study. This feature also introduces the possibility to include the effect of "negative friction" by entering negative values.

This selection is made in the "Advanced setup" dialogue box (Job menu > General data > "Foundation elements with external fixity" option > "Advanced settings" option).

Piles III: Lateral stability analysis (new module)

In version 2025.d, the CYPECAD, CYPE 3D and Foundation Elements programs incorporate the lateral stability analysis module to facilitate the design of deep foundations subjected to significant lateral forces.

This module complements the structural check of reinforced concrete piles (if your licence includes the "Piles II: Structural check" module), by allowing the checking of pile sections and reinforcements under various loading scenarios. For this purpose, the soil characteristics are integrated by means of p-y curves, and the non-linear behaviour of the soil is considered in the analysis.

The analysis is carried out using the OpenSees© analysis engine and is based on a finite element model where the behaviour of the soil is assimilated to a series of non-linear springs. The stiffnesses of these springs are determined according to the geotechnical parameters previously defined in the specifications of the soil layer.

The forces and displacements obtained at each point can be viewed on screen and exported to a CSV file. Furthermore, if your license includes the "Piles II: Structural check" module, the calculated forces are used to check the reinforcement of the pile section in accordance with the applicable codes.

To use this module, the following permissions are required in the license, depending on the program to be used:

  • In CYPECAD
    "CYPECAD", "Pile caps", "Piles III: Lateral stability analysis" and "OpenSees©. Professional version".
  • In CYPE 3D
    "CYPE 3D", "Pile caps", "Piles III: Lateral stability analysis" and "OpenSees©. Professional version".
  • In Foundation elements
    "Foundation elements", "Piles III: Lateral stability analysis" and "OpenSees©. Professional version".

Piles II: Structural check (new module)

In version 2025.d, the CYPECAD, CYPE 3D and Foundation elements programs incorporate structural checking of reinforced concrete piles for deep foundations.

The new module "Piles II: Structural check" complements the design of this type of foundation, verifying the safety of piles as a structural element of reinforced concrete according to the criteria of the selected codes.

The program can be used to easily define the section of the piles and their reinforcement and to check their resistance to the forces transmitted by the pile cap to the pile head. If the lateral stability analysis is carried out, the stresses obtained from this analysis are also taken into account. The lateral stability analysis is part of the other pile module implemented in this version "Piles III: Lateral stability analysis".

In the "General data > Foundation elements with external fixity" panel, some options have been implemented that allow considering minimum values of the bending moment and axial force to be considered, as well as setting the buckling length of the pile for the calculation. These values can also be modified for each pile cap individually.

The verification has been implemented for the entire collection of codes available in the CYPECAD, CYPE 3D and Foundation elements programs.

To use this module, the following permissions are required in the license, depending on the program to be used:

  • In CYPECAD
    “CYPECAD”, “Pile caps” and “Piles II: Structural check”.
  • In CYPE 3D
    “CYPE 3D”, “Pile caps” and “Piles II: Structural check”.
  • In Foundation elements
    “Foundation elements” and “Piles II: Structural check”.

"Piles II: Structural check" and “Piles III: Lateral stability analysis” (new modules for CYPECAD, CYPE 3D and Foundation elements)

Version 2025.d includes two new modules for checking and analysing piles (Piles II and Piles III) in CYPECAD, CYPE 3D and Foundation elements.

In the previous version 2025.c, the Piles I module was already implemented in the same programs. Therefore, as of version 2025.d, users of CYPECAD, CYPE 3D and Foundation elements have three pile modules that complement the design of deep foundations using pile caps. The three pile modules are the following:

  • Piles I: Calculation of sinking load (v.2025.c)
    This module, already implemented in the previous version (2025.c), is used to verify the bearing capacity of reinforced concrete piles under different loading conditions, taking into account the characteristics of the soil and of the pile itself. More information on this module can be found in the new features of version 2025.c.

    In version 2025.d, the Piles I module includes a new feature in the pile sinking resistance analysis by allowing the selection of two analysis modes. More information on this can be found in the new feature of this version "Analysing the sinking resistance of piles using allowable bearing pressures".
  • Piles II: Structural check (v.2025.d)
    Implemented in this version (2025.d), Piles II offers the possibility to easily define the pile section and its reinforcement, and thus to check its resistance against the requesting forces transmitted by the pile cap to the pile head. More information on this module can be found in "Piles II: Structural check (new module)" in the new features of this version.
  • Piles III: Lateral stability analysis (v.2025.d)
    Also implemented in version 2025.d, Piles III incorporates the lateral stability analysis to facilitate the design of deep foundations subjected to significant lateral forces. This module can be used to carry out the checks of the "Piles II: Structural check" module (if it is included in your license) also considering the lateral forces transmitted by the pile cap to the head of the piles. The analysis is carried out using the OpenSees© analysis engine and is based on a finite element model where the behaviour of the ground is assimilated to a series of non-linear springs. More information on this module can be found in "Piles III: Lateral stability analysis (new module)" in the new features of this version.

To use this module, the following permissions are required in the license, depending on the program to be used:

  • In CYPECAD
    “CYPECAD”, “Pile caps” and the pile modules you wish to use.
  • In CYPE 3D
    “CYPE 3D”, “Pile caps” and the pile modules you wish to use.
  • In Foundation elements
    “Foundation elements” and the pile modules you wish to use.

In addition, in any of the three programs listed above, the user license must also have the "OpenSees©. Professional version" if the "Piles III: Lateral stability analysis" module is one of the modules being used.

Piles: Calculation of sinking load (new CYPECAD, CYPE 3D and Foundation elements module)

In version 2025.c, the calculation of the sinking load in deep foundations using reinforced concrete piles has been implemented for the "CYPECAD", "CYPE 3D" and "Foundation elements" programs. This implementation has been included in the new module "Piles: Calculation of sinking load".

This module complements the design of deep foundations using pile caps, allowing users to verify the bearing capacity of piles under different load conditions, considering the characteristics of the soil and the pile itself.

To use this module, the user license must have the appropriate permissions depending on the program where it is to be used.

More information on this module common to the CYPECAD, CYPE 3D and Foundation elements programs is available in the new 2025.c version "Piles: Calculation of sinking load (new module)".

Piles I: Calculation of sinking load (new module)

In version 2025.c, the calculation of the sinking load in deep foundations using reinforced concrete piles has been implemented for the "CYPECAD", "CYPE 3D" and "Foundation elements" programs. This implementation has been included in the new "Piles: Calculation of sinking load" module.

This module complements the design of deep foundations using pile caps, allowing users to verify the bearing capacity of the piles under different load conditions, considering the characteristics of the soil and the pile itself.

The program allows users to define several ground types, including cohesive soils, granular soils and rock formations. Each soil type can be configured with its specific geotechnical properties, allowing a customised analysis of the site characteristics. Furthermore, the defined soils can be reused, which optimises the modelling and design process. Piles can be either precast or cast-in-place, with square or circular cross-sections.

The resistance to sinking is obtained by considering the resistance per tip and shaft of the soil layer in contact with the pile. The calculation method used is based on analytical formulations based on the Mohr-Coulomb equation taken from the existing specific technical specifications. The verification has been implemented for the entire set of codes available in the CYPECAD, CYPE 3D and Foundation elements programs.

The "Check "option, accessible from the editing panel of the foundation elements, allows users to consult the calculations made to verify the safety of the piles.

To use this module, the following permissions must be included in the license, depending on the program where it is to be used:

  • In CYPECAD
    "CYPECAD", “Pile caps” and “Piles: Calculation of the sinking load”.
  • In CYPE 3D
    "CYPE 3D", “Pile caps” and “Piles: Calculation of the sinking load”.
  • In Foundation elements
    "Foundation elements” and “Piles: Calculation of the sinking load”.
