起振機試験による連成基礎の振動特性について

Abstract

To evaluate the effect of an adjacent foundation on the vibrational characteristics, we carriedout the vibration tests on three kinds of foundation systems rested on the field ground: I.e., singlefoundation, two coupled foundations which are apart from each other, and two connected foun-dations which are filled with the concrete in the bottom of a space between these foundations.These systems are excited by an eccentric-mass vibrator in the vertical direction, in the horizontaldirection of parallel to the two foundations, and in the horizontal direction of perpendicular tothe two foundations. The experimental results are shown in graphical forms, and discussed indetail comparing with the theoretical results.
