Modeling of beam-column joints

Hello, STKO Team:

I am building a beam-column-slab joint model. In order to better simulate the experiment and simplify the connection of BTED and PC column into rigidlink, two node link is used for the bolted connection between BTED and the end plate. I have tried many ways to connect the nodes. However, the model does not converge. I don't know what the problem is. Can you help me modify the model (The model is in the attached zip package) ?

Thanks very much.

Ps:Here is the Disassembly diagram of the model

Here is the established model in STKO (hiding some of column properties for better presentation)

Hi, There is one issue with your model - review at how you model the connection between the beam and slab. Attached figure shows the issue. Also, I don't think you can aggregate section response in dispBeamColumn elements, only forceBeamColumn works with the aggregators. There may be other issues as well. Thnak you.
