ABSTRACT:
The present invention provides a vibration restraining structure comprising a pair of wall members defining an inner space therebetween, separation walls separating the inner space into chambers, and a liquid retained in the chambers and having a free surface.
The liquid retained in the chambers slosh as the building vibrates. Vibrational energy of the building is transferred to the liquid and generates sloshing thereof. As a result, vibration of the building is restrained. Vibration of the building is restrained most effectively when a natural frequency of the sloshing coincides with a natural frequency of the structure. In other words, the building and the liquid form a unitary oscillating system, and a fundamental vibration mode of the system is a mode wherein sloshing occurs together with a displacement of the building.
The method for restraining vibration of a building comprises a step of providing the above-mentioned structures at locations where the model displacement of the building is significant.
