OPTIMAL HYBRID BASE ISOLATION AND MR DAMPER
In this paper, optimal design of hybrid low damping base isolation and magnetorheological (MR) damper has been studied. Optimal hybrid base isolation system has been designed to minimize the maximum base drift of low damping base isolation system where for solving the optimization problem, genetic algorithm (GA) has been used. In design procedure the maximum acceleration of the structure has ...
متن کاملMULTI-OBJECTIVE SEMI-ACTIVE BASE ISOLATION SYSTEM
Semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. In this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (MR) damper has been studied for co...
متن کاملSemi-active Base isolation System for Buildings using MR Dampers
Due to limitations on the use of passive base isolation systems which show poor performance in near field seismic excitations or active systems which require high external power, as stand alone control devices for a range of seismic excitations, a hybrid control system that mitigates the limitations of either passive or active control systems is preferred. The present study examines the use of ...
متن کاملHybrid Controlled Base-isolation System with Semi-active Magnetorheological Damper and Rolling Pendulum System
A series of large-scale experimental tests is conducted on a mass equipped with a hybrid controlled base-isolation system that consists of rolling pendulum system (RPS) and a 20 kN magnetorheological (MR) damper. The 12-ton mass and its hybrid isolation system are subjected to various intensities of nearand far-fault earthquakes on a large shake table. Fuzzy controllers use feedback from displa...
