PRESTRESSED CONCRETE IN INDIAN ROAD BRIDGES

The successful completion of the Palar bridge in 1955 ushered in the era of prestressed concrete for the construction of road bridges in India. The three decades since then have seen the construction of several types of bridges in prestressed concrete, commencing with simply-supported spans and followed by more sophisticated forms of construction. The path of development taken in India has, however, differed from that prevailing abroad in certain respects in that local conditions have favoured the adoption of long spans and have militated against the use of prefabricated pretensioned units in prestressed concrete road bridges. The trend in the future will be towards the adoption of even longer spans and will call for changes in the concepts prevailing today. Optimisation will also involve changes in the codes of practice to permit the use of limit state methods of design and partial prestressing. There is also scope for the use of lightweight concrete in combination with concrete of normal weight or by itself. (Author/TRRL)
