Abstract:
Passive energy dissipation systems are mechanical devices which could spread input energy, reduce response and decrease possible damage of the structure. Dampers were identified as a strong energy dissipation devices with cost efficiency and easy installation and maintanance. In this study, effects of using friction and metallic yield dampers to reduce structural responses are investigated. In addition, a comparison between these devices for reducing responses are conducted. Two 5 and 10 stories buildings with intermediate steel moment frames with and without damper are modeled and designed. It is seen, using of dampers could be reduce sections’ sizes. Seven pairs of earthquake records scaled according to ASCE 7-10 and used in non-linear time history dynamic analysis of structures using PERFORM3D software. The results show that the friction damper on average leads to a %21 reduction in 5 stories and %22 in 10 stories building responses, and yielding damper on average leads to a %22 reduction in the 5 stories and %12 in the 10 stories building responses
