Abstract :
The culverts are required to balance the flood water on both sides of earth embankment to reduce flood level on one side of road thereby decreasing the water head consequently reducing the flood menace. Culverts can be of different shapes such as arch, slab and box. These can be constructed with brick, stone or reinforced cement concrete. Since culvert passes through the earthen embankment, these are subjected to same traffic loads as the road carries and therefore, required to be designed for such loads. The scope of this has been further restricted to the structural design of box. The structural design involves consideration of load cases and factors like live load, effective width, dispersal of load through fill, impact factor, co-efficient of earth pressure etc. The structural elements are required to be designed to withstand maximum bending moment and shear force. So excel program is developed for analysis and it is compared with software results. So analysis of box culvert is carried out for it for various box conditions and structural design is suggested for critical cases. In skew box culvert various angles are considered and analysis of box culvert is carried out for various conditions.
