Thanks, Jim. 

The problem has not been resolved yet! I have checked all the units and they are consistent. Regarding the erosion algorithm, for concrete, I'm using CSC with ERODE = 1.1. Steel is modeled using Piecewise Linear Plasticity and plastic strain at failure has been defined.

The messages I received in most of the previous attempts were negative volume warnings (no error messages) and in some other cases, I got out-of-range moments and NaN!
