Can you submit a larger image or the model itself for further investigation?

I looked into your model and could see that you have used Bonded Contacts at all interfaces.
It seems the contact detection between the joist and the plated couldn't happen efficiently at some of the locations. This is possibly caused by the relatively poor mesh that is generated, because of which there aren't enough nodes available on plate in front of the joist bars. Since there is no detection the plate is seen to traverse through the joist, which is impractical.
To fix this, you may have to add mesh manually for this case. The mating surfaces are relatively thin compared to the overall plate size and hence the automatic meshing is not producing best results. I tried refining mesh on the plate and could see the results improved significantly as there were more nodes in vicinity to establish contacts.
I'd suggest to project the joist surface on plate and control mesh locally for better results. While this will help in producing more realistic results, it will also keep the overall mesh count in check which may shoot high if the overall mesh on plate is refined without projections.
Please give it a try and do let me know if you seek any further help.
