Paper Abstract

The proposed toggle vibration controller is an excellent vibration-controlling device that efficiently absorbs seismic energy input into a building by amplifying small relative story displacements using a lever mechanism. And we tried to adopt the toggle mechanism as a lever mechanism. This is a brace-shaped passive response-controller installed in a column-beam frame of a building. It can minimize the response displacement and response acceleration by earthquakes, and is applicable independently of the type of construction, including steel-framed structures and reinforced concrete structures. The response-controlling effect is excellent for both newly built structures and seismic retrofit. This paper reports on seismic retrofit of existing reinforced concrete buildings using these devices.
