The advantages due the employment of the dissipative system for improving the seismic performance of semi-continuous steel frames in the case of both low and high intensity earthquake ground motions is pointed out. The design of the hybrid system is faced by solving a SDOF problem first, and then by considering the MDOF response related to the multi-storey coupled frame’s behavior. On the basis of the proposed procedure the dissipative bracing for the seismic up-grading of a six-floor semi-continuous steel frame was designed. The seismic performance of such equipped system was then analyzed through incremental nonlinear dynamic analyses that allowed to check the accuracy of the design strategy as well as to point out the advantages given by the coupled system compared to those of the bare semi-continuous steel frame.
