# Pile Interaction \[CUG]

## General

**Template:** The code check template is utilized to extract global parameters, results from finite element analysis, and limit states employed in the design process.

**Pile Cap:** Pile cap, pier or bent for code check. The detailed report will include information about all piles located under the pile cap.

**PDF Name (Export):** This parameter allows the name of the code check document to be modified when saving it as a PDF. When renaming the file, special attention must be given to the text characters on the [linked](https://docs.openbrim.org/faq/general/faq-illegal-chars) page, as certain characters may interfere with parametric equations and lead to unexpected results.

## Analysis Parameters

**Pile Name and Station:** Specifies pile name and associated station locations for interaction analysis.

**Section:** Section definition for the piles being analyzed.

**Axial Resistance Formulation \[From Pile Category/Override]:** Chooses how the axial-resistance formulation is selected. **From Pile Category** uses the pile's Pile Category (Drilled Shaft / Driven Pile / Micropile) to auto-select the AASHTO article; **Override** lets the user pick the AASHTO article directly.

**Pile Category (readonly):** Displays the Pile Category resolved from the pile/pile-layout object. Informational only; change the category on the pile itself.

**AASHTO - Axial Resistance Formulation \[5.6.4.4/6.9.4.1/6.9.5.1/6.9.6.3/10.9.3.10.2a/10.9.3.10.2b]:** AASHTO article used to compute axial resistance when Axial Resistance Formulation is set to Override.

**φ Compression:** Resistance factor for compression design calculations.

**φ Tension:** Resistance factor for tension design calculations.
