As an example of this vibration damping structure, as shown in FIG. 11, there is a structure in which adjacent buildings 56 and 58 are connected by a damper 60 to simultaneously reduce the shaking of the earthquake.

In addition, since the rigidity of the building 56 and the rigidity of the building 58 are generally almost equal, there is not much phase difference at the time of vibration, and the force for reducing the seismic force is small. Furthermore, since the absorption points of the seismic energy are concentrated between the building 56 and the building 58, the vibration damping effect is small.
