Design and Retrofit Methodology for Building Structures with Supplemental Energy211 Dissipating Systems

摘要

The study described in this report focuses on fundamental issues related to the211u001edesign and use of supplemental damping devices in building structures. The 211u001eprinciple objective is to develop a generic/practical analysis and design 211u001emethodology for structures that considers structural velocities and equivalent 211u001eviscous damping of the devices. These two issues are explored in depth. Tools to 211u001etransform the spectral velocity to an actual relative structural velocity are 211u001eprovided, and a simple design procedure which incorporates power equivalent 211u001elinear damping based on actual structural velocities is presented. The 211u001eeffectiveness of the design methodology is demonstrated with a retrofit design 211u001eexample using a supplemental load balancing tendon configuration.
