Hi i am looking for help on Post Tensioned Box Beam girder bridge assessment.I have modelled the bridge as 2D Grillage.I have split the box beam into I section and C section at ends.I would like to know that how can you calculate stressess in the web & diaphragm opening in 2D Model.
The Box Section details are as below:-
width -2300mm
Varying Height 1.4m to 3.5m.
Top Slab-300mm
Bottom Slab-300mm
Web thickness-500mm
The 4nos of tendons are located at junction of top flange & web.
There top & bottom reinforcement in top & bottom flange.
Any help would be great.
