Non-composite I beam section
Non-composite I beam section
(OP)
Hey guys,
i currently design a bridge deck with a non-composite I beam section (reinforced concrete slab rested on two steel beams with no fixed attachment)for simplcity using FEM. What will be the restraint of the connection between concrete and the top flange of steel if the deck is a non-composite system? is it a pinned connection?

Well there is a vertical connection.
As for how the connection should be modelled, that depends on how the beams are modelled. If it is a 3D model, with the steel and concrete members at a different elevation, then you would have to insert rigid links to the elevation of the interface, and a friction connection at the interface to allow slip at that surface. If it is a 2D grillage model the centroid of all the members will be at the same elevation, so the effect of the offset won't be included in the model anyway.

Also why use shell elements for the steel beams, rather than beam elements?
