Joint2D Element and Convergence

[Yang Zhang]

Dear STKO operation team, good evening. I am a beginner of STKO. STKO is very convenient to use.Now I have a tricky problem:
My model adopts Joint2D element, which can not converge during hysteresis analysis of this model.
I sent my model to you together. If it is convenient for you, can you help me solve this problem ？
This problem bothers me very much. I sincerely hope for your help. I wish you a happy life!

The model was not running for 2 reasons:

• you forgot to mesh the model
• the quadrilateral face used for the Joint2D element should follow the same node numbering given in OpenSees:

  Starting from the right spring in counter-clock-wise order
