Bearing Parameter Reference

The bearing parameters specify the height and positioning of the bearings respective of the girders and piers of the assembly.

Parameter Description	Content Parameter	Parametric Value	InfraWorks Set/Read	Inventor	Revit
* Overall assembly height	BearingAssemblyHeight	The total height of the bearing.	Yes/No	No	Not applicable
* Extra height	ExtraHeight	The additional distance required to stretch the bearing so it fits in the gap between the girder and pier.	No/Yes	No	Not applicable
* Girder soffit logitudinal slope	GirderSoffitLongiSlope	The required girder soffit slope angle in the longitudinal direction (the Y-axis of the part).	No/Yes	No	Not applicable
* Girder soffit transverse slope	GirderSoffitTransSlope	The required girder soffit slope angle in the lateral direction (the X-axis of the part).	No/Yes	No	Not applicable
* Pier cap logitudinal slope	PierCapLongiSlope	The required pier cap slope angle in the longitudinal direction (the Y-axis of the part).	No/Yes	No	Not applicable
* Pier cap transverse slope	PierCapTransSlope	The required pier cap slope angle in the lateral direction (the X-axis of the part).	No/Yes	No	Not applicable

Note: The single asterisk "*" indicates that a parameter is a geometry parameter that is required, and has been marked as a 'key' parameter in Autodesk Inventor.

Vertical Placement

Each bearing must set to the total height of the bearing. This value creates enough space for the bearing between its girders and supports. If the top surface of a support, and the aggregate bottom surface of the girders above are not parallel, then it is not possible to make all the gaps between them exactly. One bearing below a girder is specified with the Overall assembly height parameter. Remaining girders will adjust with the Extra height parameter.
