# V Shape Pier Cap \[CG]

The V Shape Pier Cap models a pier cap formed by two inclined limbs meeting at the base, giving the V profile used where a wide deck must be carried on a narrow footprint.

## General

**Location:** Support line the pier cap is placed at.

**Left Limb Section:** Cross-section assigned to the left limb.

**Right Limb Section:** Cross-section assigned to the right limb.

**Limb to Center Trans. Dist. Top:** Transverse distance from the centerline to a limb, measured at the top of the cap (default: 300).

**Limb to Center Trans. Dist. Bottom:** Transverse distance from the centerline to a limb, measured at the bottom of the cap (default: 80).

**Left Limb Slope:** Additional slope applied to the left limb (default: 0).

**Right Limb Slope:** Additional slope applied to the right limb (default: 0).

**Top Elevation Offset from Alignment:** Vertical offset of the top of the cap from the alignment elevation.

**Height:** Overall height of the pier cap, from the base of the V to the top (default: 240).

**Transverse Offset of Center:** Transverse offset of the cap centerline from the alignment (default: 0).

**Longitudinal Offset:** Longitudinal offset of the cap from the support line, measured along the alignment (default: 0).

## FEM

**Generate FEM?\[Yes=1/No=0]:** Setting this to No disables the analytical representation of the pier cap (default: Yes=1).

**Rigid Section:** Section used for the rigid links that connect the bearings and columns to the cap.

**Additional Break Points List:** Extra break points inserted into the cap's finite-element discretization.

**Vert. Dist. From Top of Sect. to Bottom of Bearing:** Vertical distance from the top of the cap section to the underside of the bearings (default: 0).

**Mesh Size:** Maximum finite-element size used when meshing the cap (default: 120).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openbrim.org/templates/custom-girder-bridge-workflow/substructure-cg/pier-cg/v-shape-pier-cap-cg.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
