The answer is yes. Validation and verification of the CBFEM solution is the essential part of the process of IDEA StatiCa software development. There has been extensive research done in this field, which is available partly on the IDEA StatiCa webpage or CBFEM webpage or in the book "Component-based finite element design of steel connections" by Prof. Frantisek Wald.
