Document Type: Proceeding Paper

Part of: Structural Engineering in Natural Hazards Mitigation

Abstract:

The structural properties of a new stiffness decoupler developed by Hu, Kirmser and Swartz at Kansas State University, and its applications as an energy absorber and a device to isolate structures from ground motions is presented. A formula useful for the control of the natural frequency of a structure, which incorporate the stiffness decoupler, is presented. Its use allows the designer to select any desired natural period of the structure being designed. Procedures to reduce both wind and earthquakes hazards is illustrated.
