✦ Synopsis

A study has been made of the use of three semi-active friction devices, herein referred to as dampers, to control the seismic response of a building modelled as three masses. With a pseudo-random earthquake input, peak lateral accelerations, inter-storey drift and base displacement relative to ground can be reduced by up to 50% of the values in the passive case. The relative e!ectiveness of each damper is assessed. The damper between the base and the ground is, as anticipated, the most useful.

## Abstract In this paper a predictive control method especially suitable for the control of semi‐active friction dampers is proposed. By keeping the adjustable slip force of a semi‐active friction damper slightly lower than the critical friction force, the method allows the damper to remain in its

Semi-active control of friction dampers has been proposed to improve the energy dissipation characteristics of passive friction dampers and to broaden the areas of application in which they can successfully be used. In this paper, we propose control laws for friction dampers which maximize energy di

This paper presents the "rst application of a semi-active damper system to an actual building. The Semi-active Hydraulic Damper (SHD) can produce a maximum damping force of 1000 kN with an electric power of 70 W. It is compact, so a large number of them can be installed in a single building. It is t
