In order to provide the results, the Theory of Plastic Mechanism Control (TPMC) has been applied to a large number of steel frames with different geometrical configurations and different loads and steel grades. TPMC is based on the extension of kinematic theorem of plastic collapse to the concept of mechanism equilibrium curve that allows accounting for second order effects that are very relevant especially in MRFs. This wide parametric analysis has been carried out on more than 100000 cases pointing out that for ordinary and regular MRFs type1 mechanism is the one controlling the failure mode. In these last case, a simplified application of the Theory of Plastic Mechanism Control can be used.
