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.
