Superstructure Tab
This tab contains control buttons to invoke the analysis/design programs, and features 2-D plan, elevation and cross section views with dimensions of the bridge superstructure.

| Setting | Description |
|---|---|
| Precast/Prestressed Girder Button |
This control button is used to invoke Precast/Prestressed Girder, and will be grayed out if a box girder or slab bridge is in focus. Upon execution, the LEAP Bridge Concrete database file is read into Precast/Prestressed Girder. If this file has been invoked in Precast/Prestressed Girder previously, it will be updated with Precast/Prestressed Girder specific data and will be ready for additional data entry and modification. |
| CIP RC/PT Girder Button |
This control button is used to invoke CIP RC/PT Girder, and will be grayed out if a precast girder bridge is in focus. Upon execution, the LEAP Bridge Concrete database file is read into CIP RC/PT Girder. If this file has been invoked in CIP RC/PT Girder previously, it will be updated with CIP RC/PT Girder specific data and will be ready for additional data entry and modification. |
| Design Spec |
This field shows the Design Spec that was last saved or used in Precast/Prestressed Girder or CIP RC/PT Girder, and identifies the design specifications. |
| Upper Graphical View |
This view is a 2-D plan view of the bridge superstructure, showing the position of girders or the webs in a box girder bridge. |
| Middle Graphical View | This view is a 2-D elevation view of the bridge superstructure with dimensions. |
| Lower Graphical View |
This view is a 2-D view of the bridge cross section with dimensions. The slider to the left of the view is used to select the location where the cross section is shown. Note that this cross section is viewed in a plane that is perpendicular to the alignment. |
| Single Beam View |
Check this option to view the cross section of only one selected beam in the lower graphical view (including strands and negative rebars in the deck, if any). The middle graphical view shows the side elevation view of the selected beam (including stirrups, if any). |
