Effective Configurations of Active Controlled Devices for Improving Structural Seismic Response
Abstract
Improving structural seismic response using dampers became a widely used method in the recent decades. Various devices were developed for seismic protection of structures and appropriate methods were proposed for effective design of control systems. An actual problem is how many dampers should be used as is their optimal location for yielding the desired structural response with minimum cost. A method for finding effective dampers’ placement and using amplifiers for dampers connection was recently proposed in the literature. The current study presents analyses of the amplification and placement of active controlled devices on the efficiency of a control system. A model of a twenty-story structure with active control systems including different dampers configurations is simulated. The response of the structure to natural earthquake excitations is also reported. The results of this study show a method of selecting proper configuration of active devices allowing cost effective control.
