| Abstract | There are many passive energy dissipating devices designed to dissipate earthquake energy in a structure. Metallic yielding dampers is one of these devices which is very efficient as they dissipate seismic input energy through a hysteretic behavior. This research used ETABS software to analyze the performance of three metallic yielding dampers; X-shaped damper, Double X-Shaped and Comb Teeth Damper. The story response data obtained from the analysis are story displacement, story drift and story shear. Each damper has three types of material; A992 steel, A36 steel and Aluminium. Concentrically braced frames with Chevron bracing were used and the dampers were placed in brace to beam orientation in each frame. The two types of frames analyzed was; low rise building with five storeys and a high rise building with twenty storeys. The site location for both structures were in the region of California in the United States of America. The structures were analyzed by subjecting them to three earthquakes Loma Prieta, Northridge and San Fernando as they were three of the major earthquakes that struck California in the nineties. |
