000010622 520__ $$2eng$$aDynamic progressive collapse analysis faces a great number of obstacles that often lead to the collapse of the analysis prior to the actual analysis of collapse. Hence, it is argued here that a robust analysis framework should be adopted and modified to account for the different stages of collapse. The Mixed Lagrangian Formulation (MLF) that was shown to be very robust and to scale very well to large scale problems was, thus, adopted as a framework to accommodate such analysis. This approach allows the analysis of structures in the elastic and in the plastic range while automatically considering geometric nonlinearity. It is hence natural to extend its capabilities to account for strength degradation and fracture, which is the purpose of this paper.
