이력댐퍼를 이용한 비틀림 비정형 건물의 내진보강

The object of this study is to propose and evaluate the seismic retrofit methodology using hysteretic dampers. 6-story RC building constructed 16 years ago was selected and evaluated the seismic performance through static non-linear analysis, and retrofitted using hysteric dampers. Proposed procedure is to adjust the stiffness of flexible bent frame to the stiffness of stiff bent frame to restrain the eccentricity of the building. The seismic performance of the retrofitted building increase about 1.5 times compare with original building.
