Purpose: Used to define horizontal curvature of girder. (RAD is generated in Girder System Projects from RAD-i data in girder system input, and must not be changed by the user.)
--> Given in girder input
A list of horizontal radii of curvature (feet or meters) to center of web by tenth points, beginning at the left bearing. Regions having no curvature are defined as RAD 0. Positive values indicate clockwise horizontal curvature in plan view, from the beginning to the end of the bridge. (Default is 0.) RAD data is generated in girder input from girder system layout in Girder System Projects.
Note: The central angle in a parallel/concentric girder system project is limited to 120 degrees.
