In this paper, the seismic performance of two structures of different overall typologies, namely frame and shear wall are compared. To this end, two types of earthquake ground motions and various soil conditions are considered in the definition of seismic inputs. The consistency of the Eurocode No. 8 requirements concerning the local ductilities when compared with the real demands is also analysed. In a first phase, single degree of freedom analyses are carried out with the earthquake loading prescribed in EC8. The effect of initial natural frequency and yielding level is highlighted. Having identified the main aspects of the non-linear response, a more refined modelling of a frame and a shear wall is performed, in order to verify the validity of the results obtained from the single degree of freedom calculations. The results demonstrate the superior structural performance and the cost benefit of the ductile design for earthquake resistance. Moreover, good agreement is found between the results of the single degree of freedom and the refined calculation results.
