Click Superstr. to activate the Superstructure Parameters screen. Information on the superstructure parameters is either automatically brought into Substructure through integration with LEAP Bridge Concrete or manually input by users.

For the latter case, in the appropriate fields, specify the number of lanes, beam height, area, inertia, C.G., barrier/railing height, slab depth, bridge overall width, curb-to-curb distance, span lengths and bridge width.

In case of a flared girder bridge, the dead load must either be imported from Precast/Prestressed Girder or input manually per bearing in Loads Screen.

When the pier type is multiple columns pier, hammer head pier, wall pier, or pile bent, input information about single girder. However, for integral pier, specify height, area, inertia for the entire bridge.

By default, the deck offset, which is the distance between center of the deck and that of the bent cap, is zero. You may also manually input non-zero value for the deck offset so that a general layout of superstructure and substructure of a bridge (e.g., a bridge with straddle bents) can be handled.
