In present study a two lane simply supported Box Girder Bridge made up of prestressed concrete which is analysis for moving loads as per Indian Road Congress (IRC:6) recommendations, Prestressed Code (IS: 1343) and also as per IRC: 18 specifications. Analysis and Design of Prestressed Concrete Box Girder Bridge – Download as PDF File (.pdf), Text File (.txt) or read online. Prestressed concrete decks are commonly used for bridges with spans between 25m and 450m and provide economic, durable and aesthetic solutions in most situations where bridges are needed. Prestress design. Incrementally launched box girder bridges.
Optimal design of a post-tensioned box girder is achievable by correct selection of design variables. 4 conducted an evaluation of flexural live load distribution factors for a series of three-span prestressed concrete girder bridges. Fully automated bridge design check per AASHTO Guide Specifications for LRFD Seismic Bridge Design 2009 has been implemented, including pushover analysis when required. The flexural design check for prestressed concrete box girder bridge superstructures has been enhanced to fully account for secondary effects from prestress tendon forces.
