Abstract

Passive energy dissipation devices have been successfully implemented in buildings around the world to reduce structural response, primarily due to earthquakes, but also for wind and other dynamic loading conditions. Passive systems do not require any external sources of power to operate and mitigate dynamic loadings. The focus of this study is to propose a new passive energy dissipation device, called bar damper (BD), for seismic response modification. A brief description of concept, placement, material properties, test setup and loading protocol of the proposed damper are presented. Also, the finite element (FE) analysis by means of FE analysis package, ABAQUS, was conducted to show the device effectiveness on the response reduction under applied load. From the results, it could be concluded that, the device dissipate a significant amount of energy together with a high strength capacity without degradation of stiffness.
