CURVE SPIRAL ON A BRIDGE DECK

File name is SPIRAL. Computer Program. Application: Used during the detailing of all bridge decks on spirals. This program computes bevel dimensions for bridge ties on the spiral of a curve. Input includes bridge identification, tie length, bevel length, spacing of each tie on the bridge, location of the beginning and ending of the spiral on the bridge, and amount of the superelevation at the beginning and ending of the bridge. Output includes documentation of the input, cumulative distance to each tie, superelevation of each tie, total bevel of each tie, and amount of bevel from low end of tie to low rail.
