BRGEO ‑ BRIDGE GEOMETRY
Purpose
To calculate the station, offset, coordinates and elevation of points of interest on a bridge. The bridge may be defined entirely on a tangent or curve, including a spiraled curve, or on a combination of tangent and curved sections. Either all or part of the bridge may be on a vertical curve. Either SI or US customary units can be used.
Input:
Vertical and horizontal geometry, roadway cross-section data, abutment positions, girder offsets, slab and girder depths.
Output:
For each point of interest, the top of slab elevation, top of girder elevation, top of pier elevation (if point lies on bearing line), station, offset from reference line, x and y coordinates. Gutter elevations are given at a specified interval.
