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.
