This paper presents some experimental results concerning with vibration propagation characteristics of the reinforced concrete structure in the actual building construction and in those of the model structure. This research proposes to make clear the similarity of the experimental results in the actual structures and those of the model structures. Some results are summarized as follows ; 1. Except the case of "ALC+woodcut" substructure, the foundation and the ground structure are both removed, the vibration propagation characteristics in the superstructure of the model are not depend on the substructure. And experimental results of the vibration propagation characteristics in the model structure are almost the same in the real structure. 2. The natural frequency obtained from this experimental results in the model structures are numerically almost equal to the values calculated by the law of model similitude. 3. Mode shapes obtained in the model experiments are similar to those in the actual experiments. 4. Though the damping ratio in the model structures is different from that of in the actual structures, it is possible to reproduce the vibration propagation characteristics in the actual structures by identification of the damping ratio from the experimental results in the model structures.
