LINTEL BEAM TYPE HYSTERETIC DAMPER USING INTERSTORY DRIFT OF RAHMEN FRAME

摘要

PURPOSE: A lintel-type hysteretic damper using inter-story deformation is provided to ensure structural stability since even if a damping plate is fractured, the collapse of lintel can be prevented. CONSTITUTION: A lintel-type hysteretic damper(10) using inter-story deformation comprises first and second bodies(11b), a vibration absorber(12), a pair of safety plates(13), and first and second wall fixing bars(14a,14b). The first and second bodies are arranged at an interval horizontally. The vibration absorber is installed between the first and second bodies, absorbs and distributes horizontal load. The vibration absorber is formed so that a plurality of damping plates and shim plates are alternately stacked. The safety plates are hinge-coupled to the front and rear of the vibration absorber.
