Abstract:
Post-tensioned simply supported pre-stressed concrete (PC) I-girder bridges are widely used
bridge system for short to medium span (20m to 50m) highway bridges, due to its moderate self
-weight, structural efficiency, ease of fabrication, low maintenance etc. This study is on design
and analysis of prestressed I- girder. Design constraints were decided using IRC 6:2010 for
loading, IRC 18:2000 for minimum dimension requirement, IRC 21:2000 for concrete stresses.
To formulate the entire problem for a couple of span under class A and class 70R loading,
obtain shear force and bending moment at regular intervals along the beam. The software
STAAD PRO is used for the analysis and design of prestressed concrete girders.
