초록

본 연구의 목적은 능동제어기의 최적 제어력을 산정하는 과정에서 추정된 응답을 사용하기 위하여 고층건물의 풍응답을 정확하게 추정하는 것이다. 응답 추정을 위하여 칼만필터를 사용하였으며, 진동대에 설치된 3층 축소모형 구조물을 사용하여 추정 정확도를 검증하였다. 사용된 모델의 시스템 행렬은 시스템 식별에 의해 얻어진 모드 정보를 바탕으로 구성되었다. 가속도 응답으로부터 추정된 변위는 변위계로 계측된 변위와 거의 일치하는 결과를 보였다. 마지막으로 태풍 무이파에 의해 가진된 실제 39층 건축물의 풍응답을 추정하였다.

The purpose of this study is to accurately estimate the wind-induced responses of a tall building structure for using the estimated responses in the process of calculating the optimal force of an active control device. Kalman filter was used for the estimation process and a 3-storied model structure on a shaking table was tested for the verification of the estimation accuracy. The system matrices of the model were constructed based on the mode parameters obtained by the system identification. The estimated displacement matched up well with the measured one. Finally, the wind-induced responses of a real 39-storied building structure excited by the typhoon MUIFA were estimated.
