Hybrid passive control techniques in earthquake engineering

Base isolated structures can be sensitive to the frequency content and magnitude of the input earthquake (EQ) ground motions. One effective method of addressing the sensitivity of base isolated structures is to add passive damping devices in the superstructure, resulting in implementing hybrid passive control techniques. In this paper, a simple comparison of various hybrid passive control techniques is performed. This paper demonstrates the comparative merits of various hybrid control techniques and assess the effectiveness of hybrid passive control technology in mitigating seismic hazard for base isolated structures.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
