Bridge Analysis

[arun sunny]

Hi
I was working on a project FE Analysis of a composite bridge
(Steel(Substructure) & Concrete(Superstructure)).
I modeled the bridge in CATIA and imported the iges file into Abaqus.
While running the analysis i found out the two parts i.e substructure
and superstructure are behaving independently. How to combine both of
them?

Also is there an option in Abaqus to plot the Bending Moment Diagram
along the span of bridge.


Thanks

I had the same problem generating the mesh with CUBIT (a quite good mesh
generator from Sandia Laboratories) and then importing the mesh in ABAQUS.
My mesh was small and a two dimensional one so I manually corrected each
node.
Usually in Cubit I try to use command as IMPRINT ALL and MERGE ALL because
It is caused by a node disconnectivities.

Someone knows better way?
Regards

Mire
