Assessment of Structural Performance of Single V/S Multi Cell PSC Box Girder with and without Transverse Prestressing for 6 Lane Bridge

Abstract

Infrastructure plays vital role in any developing country’s economic growth. Especially country like India where there is a huge demand of development of highway and railway bridges for the better connectivity. Prestressed Concrete Box girder i.e. PSC box girder is very common type of superstructure used in worldwide generally for the span ranging from 45m to 180m depending on construction method. Apart from that there are many long width deck bridges i.e. 6-lanes, 8-lanes etc. are coming up in India to control rapidly increasing traffic problem. In the present study, 6 different configurations are compared for the fixed six lane simply supported bridge i.e. 27.6 m deck Width Bridge having 50 m span. Out of 6 configurations, one configuration is taken with transverse prestressing of deck slab and in the rest of 5 configurations, one is single cell with and without internal strut, one is double cell with and without external strut and one is taken as triple cell. In all configurations results of transverse analysis and longitudinal analysis are compared and all calculations are as per IRC 112:2011 and IRC 6:2017.
