CULVERT:  Design of concrete culverts
This program performs the design of a range of reinforced concrete culverts.   The main features include:
 
  • Selection of bridge design codes including AUSTROADS 1992, SM1600, AS1597.2 and a general user-specific code.  If the AUSTROADS 1992 option is selected as the design code then hydrostatic horizontal earth presures are used.  If AS1597.2 is selected horizontal earth pressures must be explicitly defined.
  • Culvert types include crown units, closed box sections, inverted "U" shapes and boxes with pinned top and bottom slabs.
  • Live load wheel distribution includes overlapping cones or the more accurate Boussinesque bulbs.
  • The culvert can be analysed in a single unit configuration or as an external or internal unit in multi-unit runs.  If a single unit is selected earth pressure is applied to both sides.  For an external unit earth pressure is applied to one side only and for an internal unit earth pressure is ignored.
  • Sway can either be allowed or suppressed.  A lateral support will be inserted into the structural model in the plane of the top slab if there is no sway.
  • The number of nodes along the legs, base and top slab at which an analysis is performed can be defined by the user. The sections at which a detailed design is required can also be specified.
  • The number of bars, bar diameter and bar spacing can be either calculated by the program or user-specified at each design section (for both faces of the culvert unit).
