Multi-Story Coupled Seismic Energy Dissipation System with Displacement Amplification

摘要

PURPOSE: A multi-story displacement-amplifying and vibration-control system is provided to enhance absorbing and dissipating energy of a damper by amplifying the displacement of a structure caused by earthquake and applying the displacement to the damper. CONSTITUTION: A multi-story displacement-amplifying and vibration-control system comprises vertical frames(200a,200b), and a vibration control device(20). The vertical frames are installed in parallel to the column(301) of a building structure(300). The vibration control device is installed over different stories of the building structure using the vertical frames. The vibration control device consists of one damper(90) and two bracing members(83,84). One end of the damper is rotatably connected to one end of the bracing member at one node. The other end of the damper is rotatably connected to the node formed on a first vertical frame and is arranged to a second vertical frame in diagonal direction.
