In order to reduce the carbon dioxide exhaust quantity and the energy amount and the waste which becomes the global warming primary reason recently, the most efficient method was focused on the long-life building in Structural field. So in order to improve seismic capacity, new shape steel damper may be used in bolted connection, which made reuse of member impossible owing to serious brittle fracture of main member such as beam and column. To solve above problem, new type connection was developed and tested. As result of test, new type connection was shown good seismic capacity and main member such as beam and column were stable behavior.
