Additional Haunch Width: The additional haunch width is measured from both the right and left extensions of the top flange. During deck construction, the automatic haunch load computation is impacted by both the haunch thickness and additional haunch width.

Top Flange Materiall:
Web Material:
Bottom Flange Material: Hybrid girders are supported, allowing the assignment of different materials to the top flange, bottom flange, and web. Furthermore, it is possible to use varying steel materials between different stations through station-dependent material definitions.
FEA Settings
Supports: The definitions for insertion points and bearings must be followed by assigning those new bearings to girder objects. If this is not done, the bearings will not be formed, as shown in the screenshots below.
Top Flange Material: The material definition for the top flange can be made using this parameter. Materials can either be imported or assigned from previously defined ones.
Web Material: The material definition for the web can be made using this parameter. Materials can either be imported or assigned from previously defined ones.
Bottom Flange Material:The material definition for the bottom flange can be made using this parameter. Materials can either be imported or assigned from previously defined ones.
FEA Settings
Supports: On OpenBrIM, all bearings are generated at the center of the bottom plate of a Tub Girdertub girder. This applies in the case of having when there is one bearing for each per tub girder at a specific station. To change the location or assign additional bearings, this parameter can be used.

To have more than one bearing for a Tub Girder:  If two or more bearings are needed for the bottom plate of the tub girder at a specific station, the steps should be as follows. The bearings will be generated at the exact location of the insertion points as defined:
 Then, the FEA View (chosen from the top left-hand sidebar) should be as follows. |

Mesh Size (Longitudinal): The maximum distance between nodes in the longitudinal direction is specified using the longitudinal mesh size. In most cases, a smaller mesh size can be generated based on the bracing locations, deck pouring or deconstruction definitions, or section change locations.
