Convergence Problem for nonlinear problem of RC structure in Static Structural

    • Sokpanha Mao

      Dear everyone,

      I am currently working on a nonlinear problem of an RC slab with modeling without one support at the corner in Static Structural and having a problem with solution convergence.

      More details of my model could be found in here:

      Could anyone help me with this problem?

      Thank you

      For some general info and best practice see this post I wrote :

      Finally look at the force displacement graph to see that the structure reached maximum load that can be supported.

      There is no point going much beyond that (concrete models are not very accurate beyond failure, e.g., DP and MW concrete models).


      All the best
