MULTI-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 کاملOPTIMAL 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 کامل‘‘Smart’’ Base Isolation Systems
A ‘‘smart’’ base isolation strategy is proposed and shown to effectively protect structures against extreme earthquakes without sacrificing performance during the more frequent, moderate seismic events. The proposed smart base isolation system is composed of conventional low-damping elastomeric bearings and ‘‘smart’’ controllable ~semiactive! dampers, such as magnetorheological fluid dampers. T...
متن کاملPillow-Shape Base Isolation System and Its Seismic Behavior
In this paper a new isolating system is introduced for short to mid-rise buildings. In comparison to conventional systems such as LRB and HRB, the proposed system has the advantage of no need to cutting edge technology and has low manufacturing cost. This system is made up of two orthogonal pairs of pillow-shaped rollers that are located between flat bed and plates. By using this system in two ...
متن کاملOPTIMAL SMART BASE ISOLATION SYSTEM FOR MULTIPLE EARTHQUAKES
Hybrid control system composed of a base isolation system and a magneto-rheological damper so-called smart base isolation is one of effective semi-active control system in controlling the seismic response of structures. In this paper, a design method is proposed for designing the smart base isolation system in order to achieve an effective performance under multiple earthquakes. The base mass, ...
