COMPUTERIZED DESIGN OF PRECAST REINFORCED CONCRETE BOX CULVERTS

This paper describes the development of a general computer method for design of single-cell, precast reinforced concrete box culverts. The method uses the loading requirements of the American Association of State Highway Officials and the ultimate strength design approach of the American Concrete Institute. The user describes geometry and loading conditions, and the program analyzes many loading cases by the stiffness matrix method and determines the design forces by appropriate combinations of the results of those analyses. Based on the design forces, reinforcing steel is selected to provide adequate strength to resist the bending moments and axial forces. Shear stresses are checked to determine whether slab thicknesses are sufficient without shear reinforcement; no shear reinforcement is included in the design. A crack-control provision based on work by Gergely and Lutz is included. Culvert spans of 3 to 12 ft, rises of 2 to 12 ft, and burial depths of 2 to 100 ft are permitted. The top and bottom slabs of the culvert may have different thicknesses, and the side walls of the culvert may be a third as thick. Linear haunches may be specified and are taken into account in both the analysis and the design procedures. The computer program and its applications are discussed, and 2 sample problems are included.
