In recent years, a lot of engineers are engaged in research for breakdown process of building by vibration testing in order to recognize aseismic capacity. Vibration testing system needs to operate correctly to do effective examination, however in many cases specimens on the shakingtable don't move accurately because of several types of disturbances and cross-axis sensitivity. In this study, change in characteristic of specimen in appearance raised by cross-sensitivity is taken up especially. However, this study has never been investigated because vibration testing needs a lot of trouble. Therefore, undersized 3degree-of-freedom electrodynamic shaking system is used in this study. Thus the purpose is to analyze cause of a change in charactaristic of specific in appearance.
