Anyone know how to model an expansion joint of suspended concrete slab in Etabs ?

(OP)
This expansion joint don't transfer bending moment. Or simply, one edge of a RC slab sit on an edge of other RC slab.
Thanks.
Thanks.

If you're just starting out, would model everything in one model, do a save as to have two copies of the same model. And then delete structure on either side to get to two different models and then apply loads as described above.

One model with pin supports along the expansion joint. Obtain the reactions of this model, then apply these loads to the other model.
I don't think Etabs having any function for you to have an expansion joint in one model.
Thanks.

Would think the convenience and efficiency of having two separate models would trump any marginal increase in accuracy of having one.

Specifically designing and detailing for moment transfer would kind of destroy the point of having an expansion joint in my opinion. Not even sure how you'd do that with a concrete slab without allowing the slab to undergo lateral deformation independently on each side of the joint.

For separate models, Use vertical pin support only so you can have lateral displacement.
