ECCENTRIC TOGGLE ANTI-EARTHQUAKE DEVICE AND DISPLACEMENT AMPLIFYING ANTI-EARTHQUAKE SYSTEM CAPABLE OF INCREASING ANTI-EARTHQUAKE EFFICIENCY BY AMPLIFYING HORIZONTAL DISPLACEMENT OCCURRED ON A STRUCTURE BY EARTHQUAKE RESPONSE

摘要

PURPOSE: An eccentric toggle anti-earthquake device and a displacement amplifying anti-earthquake system are provided to enhance opening level to the inner space of a frame structure by reducing the encroaching level of the inner space of the frame structure due to the installation of an anti-earthquake device.;CONSTITUTION: A displacement amplifying anti-earthquake system comprises a frame structure(100), and an eccentric toggle anti-earthquake device. The frame structure comprises a horizontal member and a vertical member. The eccentric toggle anti-earthquake device is installed on the upper corner of the frame structure. The eccentric toggle anti-earthquake device comprises a damper(90) and two brace members(11~14). The other end of the damper is rotatably connected to a node formed on the upper corner of the frame structure. The other end of the brace member is rotatably connected to the node on the horizontal and vertical members of the frame structure.;COPYRIGHT KIPO 2012
