CURVE OFFSETS FOR TIES ON BRIDGE DECKS

File name is OFFSET. Computer Program. Application: Used as required for detailing all bridge decks on sharp curves. This program computes offsets from a chord to a circular curve for every tie on a bridge on a curve. This has application on severe curves where it may be necessary for certain tie details to follow the centerline of the track and for other details to follow the centerline of the span or offset chord. Input includes bridge identification, degree of curve, superelevation, and spacing of each tie on the bridge. Output includes documentation of the input, computed span length from the tie spacings, maximum midordinate offset for the span length, cumulative distance to each tie, offsets from curve to long chord for each tie, offsets from curve to offset chord tangent to curve at centerline of span for each tie, and tie depth correction for each tie due to curve running up and down bevel of tie.
