To analyze and design a reinforced concrete arch culvert  in accordance with the AASHTO Standard  Specifications for Highway Bridges using the Load Factor Design method. The arch can be fixed or tied, but must have symmetrical geometry and loading. The intrados and extrados curves can have up to three centers and a tangent.  Arch geometry can be defined by the intrados and extrados centers or by the coordinates, segment lengths and thicknesses of segments. The required reinforcement is computed by the program. 


Arch type (fixed or tied), geometry and strength data, locations of centers of curvatures, section properties, fill height, and uniform live load.


Arch geometry, radii, elastic center properties, loads and internal forces, influence line ordinates and areas of reinforcement.
