Hi,

If you do not want to observe the behavior of the studs, you can model the "full" composite behavior by "tie" constraint command in abaqus software. Also, you can model the studs with MPC constraints.

On the other hand, if you need to see the behavior of studs, you need to model studs with wire elements.

Thanks Dr. Abbas Ghadami for the reply.

I like to get a clarification in your reply. If I give MPC constraints at shank portion and head portion, is there a need for any other connector element to be provided in between the MPC constraints? Or should I just give the MPC constraint wherever required?

Dear Shaise K John,

You just use the MPC constraint to model the stud behavior. In other words, no other additional elements are needed, and only you need to connect the girder's top flange to the concrete slab with the aforementioned consttaint.

Please see the attachment paper. It is very good paper in details.

Shaise K John there is some abaqus model(file) similar to your problem in the below link;

hope to be helpful

I have modelled the studs as "unidimensional" beam elements and embedd them in concret. I get good results.
