Prestressed concrete sections are very much cheaper and effective as compared to reinforced concrete and therefore it has a wide use cases in bridges especially and other civil engineering structures. But nowadays curved geometry of bridges is the new trend going on , due to various reasons such as lack of space for transportation, construction in some densely populated areas to avoid traffic congestion. The use of computer software to model elements is much faster, and extremely cost efficient as compared to experimental studies in every engineering field. Here we are proposing a a design and analysis which involves the use of a computer software. Literature referenced to curved girder in general is very much insufficient to satisfy the need. Thus attempt is made to expand the knowledge regarding curved bridges and other structures. For large span bridges, box girder are ideally suitable due to their high torsion rigidity as compared to other sections. Hence parametric study of curved box girder using latest IRC codes is undertaken. Parameters such as prestressing force, angle of curvature and tendon location. It has been observed in theses system that stress variation are different as compared to straight girder. Span length is considered constant through the whole variation in section. Analysis of prestressed curved box girder is done by using finite element based Midas Civil16 v2.2 software. The aim of this study is to correlate the total shear, torsion and bending of prestressed concrete girder of structure according to different models corresponding to the above mentioned parameters and to asses the ambiguity associated with these models.
