Analysis and Design of Integral Flyovers/Bridges (Comparison of Integral Bridge with Conventional Bridge)

In general Flyovers/Bridges are built with conventional method. In conventional method various elements like Bearings, Expansion joints need regular inspection and maintenance. The expansion joints and bearings, by virtue of their functions are sources of weakness in the bridge and there are many examples of distress in bridges, primarily due to poor performance of these two elements. This can be avoided by adopting Integral type of structures. Integral Bridges are the structures without joints. Integral bridges are characterized by monolithic connection between the deck and the substructure (piers and abutments). They span from one abutment, over intermediate support to the other abutment, without any joint in the deck. Integral bridges have been constructed all over the world including India. The work includes analysis and design of Integral structure by using STADD PRO software and manual analysis for simply supported structure.
