Hello Jhon, thank you for your appreciation, if it helps somebody else I would like to share some observations that I could collect, the combinations of elements and materials that I considered:

Solid185+beam 188 type elements, They have stable behavior

Solid185+ereinf264, there is a compatibility between both elements

Solid185+reinforcement, there is compatibility between both elements

When using elements 264, stresses can only be checked using APDL commands in the Solution menu

 

 

CPT215+solid185 as reinforcement bars. According to comments reviewed in other forums, the solid element CPT215 is not suitable for modeling concrete. Due to the shape of the stirrups shape inside the column, it is not possible to have a geometry with hollow solids. When modeling hollow solids too many errors are generated in the geometry of the solid. When modeling both as solids, the concrete and the reinforcement bar as overlapping, errors getting the mesh will be generated, it happens with any of the topology options.

CPT215+beam elements  or reinforcement: Ansys does not recognize the interation between these elements.

The use of  concrete materials included in Ansys library offers betters and stable outcomes.

 

I have reviewed some information about Transient analysis and explicit dynamic analysis but did not go into depth. That I have read that some authors have managed to obtain complete hysteresis loop from their concrete model, if you have any suggestions about these topics it would also be helpful.

 

And regarding the use of APDL or Python commands to exchange the material according to the stages of the analysis, elastic stage and plastic stage, I also reiterate my question, if you know anything or some examples it will help me.

 

Thanks in advance
