Analysis and Design of Prestressed Concrete Box Girder Bridge

Abstract

AbstractBridge 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.
