Comparative Analysis of Box Culvert with Cushion and without Cushion Using Staad Pro

Bridges are essential for the efficient movement of trains and locomotives, as well as for crossing water courses such as streams across embankments as roads are not allowed to obstruct the natural flow of water. Culverts provide balance to the water flow on both sides of the road, as well as protecting and balancing the embankment in order to reduce flooding. Different types of bridges exist, such as arch, slab, and box. Masonry brick, stone, etc. or reinforced cement concrete can be used to build them. The bridges pass through the embankment and are therefore subject to the same traffic loads that the road carries, so they must be designed accordingly. Depending on where the bridge is located, the cushion will vary. Structures must be designed to take into account the loads empty, full, surcharge, etc. along with factors such as live loads, width, force of braking, load dispersion within the fill, impact factor, and earth pressure. Referrals are required for relevant IRCs. It is necessary to design structural elements that can withstand maximum bending moment and shear force. The culvert crosses over the earthen embankment, so it is subject to the same traffic load as the roads as a result, it has to be designed for such loads acting on the culvert surface. The present study focuses on reinforced concrete box culverts with different aspect ratios. The box culverts are analysed for varying cushion and no cushion loading. A large emphasis is placed on determining how well a structure will behave under various types of loading as recommended by IRC codes, and the combinations that will cause the most harmful effects on the structure. Comparative analysis and conclusions are based on maximum bending moments for different loading conditions.Part 1 The study deals with the planning and analysis of Box Culvert using Staad Pro software. In this study Box Culvert clear span is 5m and clear height is 3m and the slab is fixed supported. The drafting and detailing work was completed using AutoCAD software and thereafter the entire analysis work was completed using “Staad Pro v8i ss6. Part 2 Comparison of Box Culvert with cushion or without cushion also the analysis results in term of shear, bending moment, axial force and deflection were checked by STAAD Pro which is passes through many different load combinations. The maximum design moments resulting from the combinations of various loading cases. Puneet Kumar Pandey | Dr. A. K. Jha | Dr. R. S.
