# Strip Seal \[SIG]

A strip seal is an elastomeric (rubber-based) gasket used to prevent water and debris from infiltrating through expansion joints. It is typically used in combination with steel profiles and is designed to withstand traffic loads.

## General

**Approach Slab:** This parameter can be used to specify the approach slab for which the sleeper slab will be modeled.

**Strip Seal Orientation\[Transverse/Longitudinal]:** This parameter defines the orientation of the strip seal.

**Strip Seal Location\[Right/Left]:** This parameter defines the location of the strip seal.

**Sleeper Slab Head Wall:** This parameter is used to select the sleeper slab headwall object.

**Length:** This parameter specifies the length of the strip seal.

**Width (Normal to the edge of approach slab):** Width of the strip seal measured perpendicular to the approach-slab edge. Used together with **Length** to dimension the strip seal footprint.

**Joint Gap:** This parameter defines the joint gap distance.

## Left Strip Seal

**Depth:** This parameter can be used to specify the depth of the strip seal in the left direction.

**Width:** This parameter can be used to specify the width of the strip seal in the left direction.

**Length:** This parameter can be used to specify the length of the strip seal in the left direction.

**Offset:** This parameter can be used to specify the offset of the strip seal in the left direction.

**Depth Offset:** This parameter can be used to specify the depth offset of the strip seal in the left direction.

## Right Strip Seal

**Depth:** This parameter can be used to specify the depth of the strip seal in the right direction.

**Width:** This parameter can be used to specify the width of the strip seal in the right direction.

**Length:** This parameter can be used to specify the length of the strip seal in the right direction.

**Offset:** This parameter can be used to specify the offset of the strip seal in the right direction.

**Depth Offset:** This parameter can be used to specify the depth offset of the strip seal in the right direction.

## IFC

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

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

* ABUTMENT
* DECK
* DECK\_SEGMENT
* FOUNDATION
* PIER
* PIER\_SEGMENT
* PYLON
* SUBSTRUCTURE
* SUPERSTRUCTURE
* SURFACESTRUCTURE
* 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.
