The work herein presented is devoted to the comparison between two design approaches leading to the same design goal, i.e. the design of structures able to develop a collapse mechanism of global type. These selected design procedures are the Performance- Based Plastic Design approach (PBPD) and the Theory of Plastic Mechanism Control (TPMC). To this scope reference is made to several MR-Frame structures designed by means of both procedures. The seismic performances of such MR-Frames have been investigated by both push-over and dynamic non-linear analyses.
