CYPECAD/CYPE 3D - Configuring and checking the structural limit in reinforced concrete piles
The structural limit or nominal load is the calculation value of the pile's resistance capacity. In the program, you can activate the structural limit check for reinforced concrete piles and check their compliance as indicated below.
Configuration in the "Structural limit" tab
The configuration tab for the "Structural limit" check can be accessed as follows:
- in CYPECAD, within the "Foundation elements with external connection" button, next to the "Foundation" drop-down menu in the "Concrete" section;
- and in CYPE 3D, in the "Piles (reinforced concrete)" section of the "General data" window;
- then, in the "Piles (Reinforced concrete)" section, click on "Advanced settings".
Here, the structural stop is defined independently for "Driven precast pile" and "Pile cast in-situ".
This can be done in "Absolute" mode, by entering the structural stop value directly in pressure units, or in "Relative" mode, by entering a coefficient between 0.01 and 1 that multiplies the concrete strength (fc).

| The "Structural limit" tab is disabled by default in all codes except the Spanish structural code "Código Estructural". |
Structural limit check
When the tab above is enabled, an additional check will appear in the check reports for each pile cap, in the "Piles" tab, indicating whether or not it complies.
For compliance, the axial stress on each pile must not exceed the defined structural limit, considering the cross-sectional area of the pile.
This is performed for the worst combination of serviceability limit states.
