For seismic design, the installation of vibration control devices between floors is widely accepted. As the vibration suppression performance of the entire building highly depends on these devices, it is important to understand how they affect the dynamics of the building.

In this talk, a vibration control problem of a chain of masses with base excitation will be introduced in a context of seismic design. The main objective is to limit the intermass displacement (inter-storey displacement in a building) and the frequency domain analysis is used to approach this problem. It will be shown that the maximum value of the frequency responses from a ground displacement to the inter-storey displacements remain bounded as the building gets taller.
