Bridge Model > Line and Plate Elements
I am trying to model a bridge superstructure using line elements for the longitudinal girders and modelling the deck as concrete plate elements.
Why is that when I offset the deck to be at the top of the girder (using section offset) I get different bending moment output compared to a case where there are no offsets?
Please advise what the model is doing differently if I try to offset the plate element deck to be at the top of the girder.
When the section offset feature is used, software basically creates a rigid link connecting the section centroid to the offset location. Thus, a beam element would behave as if it has 2 rigid short columns at the end. Kindly refer the description provided below in our online help manual.
