ANALYSIS OF FLYOVER STRUCTURES WITH DIFFERENT LOADS

Fly - over's have been constructed since early seventies. They are mainly constructed for the purpose of traffic congestion elimination. However planning, design, construction, and erection of fly - over consume great span of time. The same have been the case with the emerging fly - over over NH By - pass, ONGOLE, and spanning 600m with a width of 6.6m. Greater seismic resistance, life span, and lesser l ife cycle cost nullify the excess cost of construction of flyover. Bridges and fly - over's are structures providing passage over an obstacle without closing the way beneath. The required passage may be for a road, railway or a valley. Bridge design is a com plex problem, calling for creativity and practicability, while satisfying the basic requirement of safety and economy. The basic design philosophy governing the design is that a structure should be designed to sustain, with a defined probability, all actio n likely to occur within its intended life span. In addition, the structure should maintain stability during unprecedented action and should have the adequate durability during its life span.For easy traffic flow of vehicles without traffic congestion flyo ver or over bridges is essential to overcome the traffic congestion required. Our project deals with the Design of a flyover in the intersection. The location is at four roads junction at pipeline junction, which is facing major traffic problems due to the construction
