Abstract
Bridge design varies broadly around the world. Many standards are presently deals with Limit
State Method. The design of various components of bridges is now done in most countries almost
invariably with the use of computers. Designers are going in for longer and longer spans and adopt
different forms and geometry in alignment. In recent years, single or multi-cell reinforced concrete box
Girder Bridge have been proposed and widely used as economic aesthetic solution for the over crossings,
under crossings, grade separation structures and viaducts found in modern highway system. The very large
Torsional rigidity of the box girder‘s closed cellular section provides structures beneath is more
aesthetically pleasing than open-web type system. In India, IRC had published IRC: 112 – 2011 that
combines the provision for the both RCC & Prestress Concrete Structures. The present paper focus on
comparative design of a box Girder bridge under IRC: 112 – 2011 and AASHTO LRFD Bridge Design
Specification. This paper addresses the differences in calculation procedure, and the resulting design. This
review paper consists of evaluate the Limit State Method of IRC: 112 and AASHTO-LRFD Bridge Design
Specification. The main aim is to study the similarities and differences between the design procedures of
IRC: 112 and AASHTO-LRFD. For that the past papers related to comparison of bridge super structure
design with reference to IRC and AASHTO standards.
