Analysis and Design of Prestressed Concrete Box Girder Bridge

Abstract
Bridge construction has now achieved global significance. In this evolution era, 
prestressed box girder bridge is becoming more and more popular the bridges as 
it has improved serviceability, aesthetic appearance, better stability, and also 
economical. It has also structural efficiency. In this research, analysis, and design 
of prestressed concrete box girder bridges are carried out using MIDAS Civil 
design software and a prestressed balanced cantilever span are selected for the 
design. For the study, the AASHTO LRFD-12 code is taken as standard. The main 
goal of this study is to determine the structural behaviour such as bending 
moment, deflection, force, compressive strength, flexural strength, crack width 
at service, principle stress, and shear stress of a three-span box girder bridge for 
different loading conditions and subsequent geometrical and material 
requirements of bridge components and also its performance at different 
construction stages.
