Bridge bearing tips
- Users may specify different girder-bearing properties at each bent and abutment. Overwrite options are located under BrIM > Bridge Object definition, under > Abutments or Bents, there are overwrite options that allow you to control the bearing at each girder.As of version 12.0.2 of the program, bridge modeler always places and Bents.
- The bridge modeler locates bearing links directly below each web and it is not possible to change this within the parametric bridge model definitionthe girder web. To model a different bearing layout, you would need to make these changes manually, outside of the bridge modeler. You would need to delete the links at the bearing location created by automatically created, then, outside the bridge modeler and then recreate these links manually. (In some special cases, you can , manually create links as desired. When girder design should not have bearings, create a bearing property with zero stiffness in along each DOF, and use that for the girders that have no bearings. This way, no modifications are needed outside the Bridge Modeler.)then assign that element to simulate the absence of a bearing.
