  • Abstract:
  • paper is focussed on the analysis and design of a flyover. Flyover is a grade separated structure connects road at different levels for the purpose of reducing vehicle congestion. The grade separator is of 100 m length with 10 spans, 10m per span. It consists of a deck slab, longitudinal girders, cross girders, pier and foundation. The structure is subjected to different loadings namely Dead load, Super Imposed Dead Loads, Carriageway Live loads etc., For the analysis, different live load cases namely IRC Class A, IRC Class 70R wheeled & tracked are considered. Also, the braking load, impact load, wind load, longitudinal forces are to be considered in the analysis. Here the structural analysis is carried out by using STAAD Pro V8i software. Structural design of one span was made for all the above components. Slab is designed by working stress method as per the recommendation of IRC: 21-2000, Clause 304.2.1. Cantilever slab is designed for maximum moment due to cantilever action. Longitudinal girders are designed by Courbon’s method. Cross girders are designed mainly for stiffness to longitudinal girders. The deck beam is designed as a cantilever on a pier. The Pier is designed for the axial dead load and live load from the slab, girders, deck beam. Foundation designed as footing for the safe load bearing in the soil. All the elements are designed by using M25 grade concrete and Fe415grade steel. Designs are based on Working stress and Limit state method as per IRC: 21-2000 and IS: 456-2000.
