Novel Controllable Semiactive Devices for Reshaping Structural Response Academic Article uri icon


  • Semiactive dampers and actuators hold significant promise for their ability to add supplemental damping and reduce structural response, particularly under earthquake loading. Novel controllable devices utilizing off the shelf components and control systems have been developed to modify structural response. The devices are presented from design, modeling, analysis, and validation via hybrid testing and experimental shake table results. All cases are compared with independent analytical predictions based on first principles analysis. © 2008 IEEE.
