AB - Recent studies on seismic control of rocking structures have proposed the use of inerters, mechanical devices that develop resisting forces proportional to the relative acceleration between their terminals. Analytical analyses have shown that these devices effectively reduce the frequency parameter of a rocking block resulting in lower seismic demands and enhanced stability due to the well-known size effect of the rocking behaviour. As with most of such strategies, the efficiency of the inerter has been assessed for perfectly rigid bodies in the first place. However, in real practical applications, rocking structures will exhibit some degree of flexibility. Moreover, some of the underlying assumptions of the analytical models used to study rigid bodies imply that the structures are slender, and therefore more likely to deform during the rocking motion. In this paper, the dynamic response of multi-mass flexible rocking bodies equipped with inerters is examined. Firstly, a numerical model is formulated and implemented in OpenSees. This model is then validated against analytical analyses of single-mass flexible structures. Subsequently, the responses of buildings ranging from 3 to 9 stories are studied and compared in terms of elastic deformations, base rotations and floor accelerations. The effect of increasing levels of flexibility in the efficiency of the inerter is also assessed.
