# Drip Bar \[SIG]

A drip bar refers to a structural element used in bridges to ensure the proper drainage of water.

## General

**Girder:** The girder to which the drip bar is connected.

**Station:** Station along the PGL.

## Top Bar

**Length:** This parameter is used to define the top drip bar's length in the transverse direction.

**Width:** This parameter is used to define the top drip bar's width in the longitudinal direction.

**Depth:** This parameter is used to define the top drip bar's depth in the Z direction.

**Angle:** This parameter is used to set the angle of the top drip bar in the longitudinal direction.

## Bottom Bar

**Length:** This parameter is used to define the bottom drip bar's length in the transverse direction.

**Width:** This parameter is used to define the bottom drip bar's width in the longitudinal direction.

**Depth:** This parameter is used to define the bottom drip bar's depth in the Z direction.

**Longitudinal Offset from Top Bar:** This parameter defines the longitudinal offset of the bottom drip bar relative to the top drip bar.

## IFC

**Type:** The IFC entity type for BIM export. Default is IfcDiscreteAccessory.

**Predefined Type:** The IFC Predefined Type is specified using this parameter. Available options include:

* ANCHORPLATE
* BIRDPROTECTION
* BRACKET
* CABLEARRANGER
* ELASTIC\_CUSHION
* EXPANSION\_JOINT\_DEVICE
* FILLER
* FLASHING
* INSULATOR
* LOCK
* PANEL\_STRENGTHENING
* POINTMACHINEMOUNTINGDEVICE
* POINT\_MACHINE\_LOCKING\_DEVICE
* RAILBRACE
* RAILPAD
* RAIL\_LUBRICATION
* RAIL\_MECHANICAL\_EQUIPMENT
* SHOE
* SLIDINGCHAIR
* SOUNDABSORPTION
* TENSIONINGEQUIPMENT
* USERDEFINED
* NOTDEFINED

**Parent \[Bridge/Superstructure/Deck/Substructure/Foundation/Approach\_Structure/Retaining\_Structure]:** The IFC Parent is specified using this parameter to define the hierarchy relationship in the IFC model.

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/steel-i-girder-bridge-workflow/superstructure-attachments-sig/drip-bar-sig.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.
