Dear All As we know for pre-stressed concrete elements the prestressing force must be applied as external load (axial and moment). It is also needed to consider initial stress and strain for tendons before the running the analysis. My question is about the modeling a simply supported pre-stressed co...

Dear OpenSees users I modeled a simply supported RC beam in opensees. The beam (rec section) consists of fiber section with Concrete02 material model to consider tensile strength for concrete. I successfully performed the gravity analysis in first step and then I applied a two-pointed concentrated l...

Do you find the solution and the reason?

Dear xavio
After 11 years . Could you please explain it. I faced with similar problem.
