Comparative Study on Construction Stage Analysis of Multi Span Conventional Bridge with Integral Bridge

Ansy M R, Dr. B G Sreedevi, Ritzy R

Abstract: Bridges are the important, useful and efficient civil engineering structure which decided the development of country. Bridges are of different types. They are designed based on the function of the bridge. Conventionally, bridges with bearing are most commonly used. The conventional bridges consist of simply supported spans separated by expansion joints and the bearings. During the service life of the bridge these expansion joints and the bearing, at the intermediate pier heads and abutments, are affected with rusting of steel reinforcement and deterioration of concrete due to the accumulation of debris and de-icing chemicals. This will lead high maintenance cost as well as the replacing cost. Hence engineers are recommended a new method for bridge construction i. e. integral bridge. Integral bridges are the bridges without joints which lead to the lower initial as well as the maintenance cost. This paper presents analytical comparative study on the construction stages of both conventional bridge and integral bridge in terms of moment and deflection by using SAP bridge software. From the above study it can be concluded that the variation in the moments and deflection during the construction stage has to be studied for a long span integral and conventional bridge. It is recommended that the integral bridges show more effectiveness than conventional bridges to avoid the accidents at the construction stages
