Numerical Verification of the Proposed Design Procedure of MR Damper for Seismic Response Control of Building Structure

건축 구조물의 지진응답 제어를 위해 제안된 MR감쇠기 설계 절차의 수치적 검증

In our previous study, we have developed a preliminary design procedure of MR dampers for controlling seismic response of building structures. In this paper, the effectiveness the proposed method is verified through the numerical analysis of the structures with various period and story number, and twenty earthquake loads are used for statistical assessment. The comparison between the proposed method and simplified sequential search algorithm indicates that the capacity, number and the placement of the MR damper which can achieve the given performance objective are reasonably determined using the proposed design procedure.
