Smart system design for a 3D base‐isolated benchmark building
10.1002/stc.228.abs
The application of control technologies to structures is expected to enhance a structure's performance in response to natural hazards. This study focuses on the development of control design strategies suitable for smart base isolation systems. The phase I benchmark problem for 3D base‐isolated buildings is used as a case study to facilitate a direct comparison with the results of other designs. The smart base isolation system consisting of passive isolators and controllable semiactive devices at the base is employed for the demonstration and validation of these strategies. Magnetorheological (MR) dampers are used as the control devices and are placed in parallel with the isolation system. An H2/LQG control algorithm is used to determine the nominal control action and is used in conjunction with a clipped optimal decision block. Effective design for this complex system requires the use of control device and sensor placement techniques achieved with the consideration of the structure's physical properties. The use of correlation is also proposed to minimize redundancies in the placement of the sensors and devices. Simulation results demonstrate that the control technique is effective in improving the structural performance for a variety of earthquakes. Copyright © 2007 John Wiley & Sons, Ltd.
