ANALYSIS OF SLIDING MOTION OF PILED MULTI-BLOCK SYSTEMS CONSIDERING HORIZONTAL ROTATION

적층 강체블록의 수직축 회전을 고려한 Sliding운동 해석과 실험

The most cultural heritages are composed of piled multi-block systems which are vulnerable to earthquakes. The stone of low height tends to slide when the excitation such as earthquake is applied and this sliding motion has effects on the whole response of the structure. In this study, analytical method of sliding motion of the piled multi-block systems considering horizontal rotation is developed and compared with shaking table test results. It is shown that the nonlinear analysis of sliding motion of multi-block system leads to satisfactory results.
