# Design calculation for box culvert

In this paper we also study about design of box culvert and comparative study of reinforcement details. Vent size of the culvert is fixed based on flood discharge from upstream side.Clear dimensions of the box culvert is 3mX3m. Thickness of slab is 400mm.Grade of concrete is M30, grade of steel is Fe415 and angle. Per Articles 12.11.2.1, 3.6.1.3 and 3.6.1.2.6, the application of live load is different for single box culverts and for multiple box culverts. Designers should apply live load to all box culverts except when: • For single box culverts, the fill height is greater than 8 feet and greater than the span of the box

The Basics of Culvert and Inlet Design Introduction The design of a culvert is influenced by cost, hydraulic efficiency, purpose, and the topography at the proposed culvert site. Thus physical data must be integrated with engineering and economic considerations Currently, most box culvert installations are provided in precast form due to the huge reduction of time for place production and construction. Design new reinforced concrete culverts and extensions to existing culverts subjected to either earth fill and/or highway vehicle loading in accordance with the AASHTO LRFD Bridge Design Specifications.
