Hi
I have designed a U frame footbridge.The fabricator has proposed to split the bridge in 3 section at cross members level. The cross members are 120x120x8mm SHS.The design loading on cross members are:-
Moment 20kN.m
Shear 20kN
Tension 22kN
The fabricator proposal is to use a plate 25mm thk...
I have modelled the above bridge as a 2D Grillage.I would like know that do you have to model the End/Anchor blocks into your model?
Any help would be great.
I am doing an assessment of a bridge which has span 1 & 4 Prestressed Beams and Span 2 & 3 Post Tensioned Beams. The beams at intermediate supports are sitting on rubber bearing pads.
I have modelled the bridge as 2D Grillage.Do I need to model the hogging section properties for the beams over...
I have modelled a U Frame footbridge as a 3D grillage but for some reasons i am getting high axial forces and moments at the bottom chord which is failing the check for combined axial & bending.The deck is at bottom chord level.
The bridge is simply supported and Span is 20m,height is 1.8m and...
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.
