진동대를 이용한 다자유도 지반-구조물 상호작용 시스템의 유사 동적 실험기법

This paper presents an effective hybrid pseudo dynamic test method for analyzing the response of MDOF systems using laboratory shake table. Hybrid shake table test combined with the pseudo dynamic method was conducted to analyze the soil-structure interaction without a large soil box. The polynomial extrapolation method was employed to predict the acceleration of the structure. To demonstrate the effectiveness of predicting acceleration, the actual experiment was performed on one part of the structure, while a numerical simulation was performed on the other part of the structure and on the soil-structure interaction. Test results show that the proposed hybrid pseudo dynamic algorithm for the substructure is reliable and accurate.
