The Support column shows the label associated with the support. The Location column provides the physical location of the support on the box girder in relation to the start of the girder. The Ref Name column shows the referenced name of the pier support. For abutments and span hinges, this name if for convenience only. The Conn column shows the type of connection between support and the superstructure.

The Horiz, Vert, and Moment columns show the horizontal and vertical force, and moment at each support or span hinge. Positive values denote compression.

Substr Long Stiffness and Dist Fac column shows the horizontal stiffness and the relative distribution of horizontal force to the frame substructure.

The Substr Lat Dist. Fac column shows the factor that is applied to the substructure stiffness when doing an analysis on an individual girder. This factor is automatically calculated by CIP RC/PT Girder using the width of a girder divided by the total width of the cross section. You may elect to have CIP RC/PT Girder not perform this automatic substructure stiffness reduction by using the option on the Superstructure dialog box.
