SAP2000 help with bridge design

SAP2000 help with bridge design

(OP)
Hey, I am trying to draw a deck (shell element-thin) supported on stringers(frame element). I draw stringers as a frame with its center-line on the center-line of the slab and then use ' Cardinal points' and 'Frame joint offsets' to get the correct positioning. When I run the analysis for dead load, the stringers do not carry the bridge deck (which deflects through them when I run animation). I do not understand what I am doing wrong.

RE: SAP2000 help with bridge design

Sometimes this is just a visual thing, since you didn't post a picture of the issue you're observing, or posting your model demonstrating the issue it's hard to say for sure. Is the load actually being supported by the girders when you review the design actions. How have you meshed the slab may have some impact on what you're seeing.
