Autonomous-decentralized semiactive control scheme for buildings utilizing MR damper based variable slip-force level damper

摘要：

This paper proposes a semiactive structural control scheme utilizing variable slip-force level dampers.A passive slip-force level damper would not dissipate energy until reaching the slip-force level and then forming a hysteretic loop.If the slip-force levels are controllable,the damper would effectively work out from small to large levels of seismic excitations.This is the basic concept of the semiactive control with variable slip-force level dampers.The control effectiveness of these dampers depends on how to determine the slip-force level.In this paper,the slip-force level is controlled based on only the measurement of the local response information.In the proposed control scheme,therefore,the slip-force level of each damper can be determined by its own decentralized microprocessor.In this paper,MR damper is utilized to realize the concept of variable slip-force level damper.The effectiveness of this scheme is demonstrated by conducting numerical simulations.
