The paper presents the results of a numerical program that was used to investigate the seismic performance of dual steel frames with dissipative shear walls. Nonlinear static and dynamic analyses were employed in order to evaluate the global ductility and the q factor for a twelve story building. The influence of the q factor on the estimated level of damage and post-earthquake intervention strategy was investigated. The dynamic analyses were conducted using two groups of accelerograms, selected to match the response spectra of two types of grounds. The numerical models were validated against experimental tests. The results show that q factor values adopted in design influence the level of damage. If re-centering capacity is properly controlled by design, the replacement of damaged walls can minimize the time and cost of intervention, thus supporting disaster resilience of buildings
