In recent years modeling methods of equivalent shear spring models for passive control structures have been proposed. However, no methods are available for configurations with multiple kinds of dampers in parallel. Thus, in this paper, a method is proposed to create an equivalent shear spring model of passive control structures with parallel configurations of stud-type viscoelastic dampers and hysteretic dampers. The parameters of the proposed model are calculated by considering the response of the structure in four states. This paper shows that the proposed modelling method can accurately reproduce the results of time-history analysis of member models.
