CYPECAD

The check of the reinforcement layout according to CIRSOC 103 in piles is configured as follows:

• in CYPECAD, in the "General data" window, under 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 configuration" and open the "Structural check" tab.

Here you will find the checkbox "Check the reinforcement layout according to CIRSOC 103".

If this box is checked, the specific reinforcement layout checks for piles are performed only according to the Argentine seismic standard CIRSOC 103, instead of using the criteria indicated in the concrete standard, regardless of whether seismic calculation is enabled for the project or not.

If it remains deactivated, the programme checks the reinforcement layout according to the concrete standard for compressed elements and, additionally, if seismic calculation is activated for the project, the criteria of the CIRSOC 103 standard will also be checked.

Configuration in the "Structural limit" tab

The configuration tab for the "Structural limit" check can be accessed as follows:

• in CYPECAD, in the "General data" window, 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).

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.

The "Base shear condition verification" can be configured from the corresponding section of the "Regulations for seismic action calculation" window, accessible by activating the "With seismic action" checkbox in "General data".

Here, you can choose one of the following options to consider the increase in base shear forces:

• Do not carry out the static base shear correction
  This option allows you to bypass the base shear check and, consequently, avoid adjusting the results.
• Based on the Code
  The factors calculated as specified in the selected seismic code are applied. This option only appears if the selected seismic standard considers the verification of the base shear condition.
• Specify the static base shear percentage (%)
  The "Percentage of static base shear" can be considered as the minimum limit in the base shear check.
• Specify the modification factors
  Applies modification factors to the dynamic calculation results specified by the user, according to their own considerations, seismic hypothesis and analysis direction ("Earthquake X1" "Earthquake Y1").
