Culvert refers to a structure that is installed under a structure for the purpose of allowing water to pass or pedestrian traffic. Midas Civil NX offers advanced tools to facilitate the design of Box Culvert, including the Structure Wizard feature, which simplifies the modelling process.
2D culverts are modelled and analysed as beams with unit widths. Since each of the walls, deck and foundation are represented by beams, bending moments and shear forces due to the external forces are extracted for 1 m length of culverts in the transverse direction. The components are designed as beam elements.
The design of a culvert involves determining the amount of reinforcing steel by examining the moment and shear force of the structure. The significant forces, such as earth pressure, moving load, and dead load, can be assumed to act horizontally and vertically in a single plane.
