SubscriberDear everyone,
I am currently working on a nonlinear problem of an RC slab with modeling without one support at the corner in Static Structural and having a problem with solution convergence.
More details of my model could be found in here: https://drive.google.com/drive/folders/1bmApGI7Stz1RPUwFRXnJoZ9sLD_8b8Ak
Could anyone help me with this problem?
Thank you

Hi
For some general info and best practice see this post I wrote :
/forum/forums/topic/how-can-we-model-failure-in-reinforced-concrete-rc-slabs/Finally look at the force displacement graph to see that the structure reached maximum load that can be supported.
There is no point going much beyond that (concrete models are not very accurate beyond failure, e.g., DP and MW concrete models).

All the best
Erik

SubscriberHello Erik,
Thank you for your recommendation
I have tried to apply displacement instead of applying axial force of 7900N that I used to apply.
I found the force reaction vs displacement curve at the corner location as the maximum force at 6890N.
Actually, my objective is to find the vertical displacement result at the corner when applying axial force and moment at the corner (the corner that does not have support).Â
May you give me some suggestions on how to overcome this convergence problem as the load condition was applied like this?
Best regards,
Panha
