Pick insertion points
Step 3: Define Fixities
Set Tx/Ty/Tz/Rx/Ry/Rz values for each bearing based on bearing type.
Fixity values
Step 4: Configure Load Transfer
Set Transfer Force to Substructure = Yes for interior pier locations
Set Transfer Force to Substructure = No for abutment locations
Quick Tip: Coordinate System
DOFs are assigned based on the local coordinate system at each insertion point, which changes along the support line and alignment. The Bearing Rotation parameter rotates the support clockwise in the XY plane.
Verification
The completed bearing fixity configuration is shown below.
