IRC:6-1966

Limit State Box Culvert Design IRC:6-1966 is a code of practice developed by the Indian Roads Congress (IRC) for the design of box culverts. Box culverts are precast concrete or masonry structures used for the passage of water under roads, railways, and other transportation infrastructures.

The design of box culverts using IRC:6-1966 involves considering the various limit states or failure modes that may occur during the service life of the culvert. These limit states include the ultimate limit state (ULS) and the serviceability limit state (SLS).

The ultimate limit state refers to the maximum load or stress that the culvert can withstand without failure. The design of the culvert involves ensuring that it can withstand the maximum loads that may occur during its service life, such as traffic loads, soil and water pressures, and seismic forces.

The serviceability limit state refers to the acceptable level of deformation or deflection that the culvert can undergo without affecting its function or safety. The design of the culvert involves ensuring that the deflections and deformations do not exceed the acceptable limits, which can affect the hydraulic capacity and structural stability of the culvert.

The IRC:6-1966 provides guidelines and procedures for the design of box culverts, including the determination of the design loads, selection of the appropriate culvert size and shape, calculation of the reinforcement and concrete thickness, and evaluation of the hydraulic and structural performance of the culvert using appropriate analysis methods and criteria.

The design of box culverts using IRC:6-1966 requires expertise in structural engineering, hydraulic engineering, and transportation engineering. The code of practice provides a comprehensive and standardized approach to the design of box culverts, ensuring that they are safe, efficient, and durable for their intended use.
