Hi, I am interested in modeling of repair of a damaged reinforced concrete column. That is, once the RC column is damaged in the plastic hinge region (e.g. cover concrete spalling & rebar yielding) under the loading, the column is repaired with fresh concrete keeping the rebars the same. I guess...

Hi all, I am trying to run transient analysis for a RC cantilever column and check the local response (stress & strain) of concrete fibers at the bottom of the column where I can see the highest strain. Here are some questions regarding it. 1. one forceBeamColumn element vs. several dispBeamColu...

Thank you for your advice. I would like to clarify if I understood correctly. Please let me know if I am still wrong. 1. You are telling me that 'zeroLengthSection Element' I used in the model represents moment-curvature relationship at a section. To be able to use it as a element, it needs to be mo...

Hi, I have a question about zero length section element. I built a RC column fixed at the bottom in OpenSees and built another RC column that has exactly the same section except that this column has a zero length section element at the bottom. Mass is attached at the top node. When these columns are...
