In addition, when columns and beams are constructed of reinforced concrete, it is necessary to construct a concrete formwork and to support the concrete formwork by supporting works or the like, which is troublesome.

Further, as a vibration control device, a device using low yield point panel steel to absorb energy at the time of an earthquake by yielding a material is also known. When mounted on a reinforced concrete column or wall, the weight of the upper column or wall may be applied to the vibration damping device, causing deformation, and failing to exhibit good energy absorption capacity during an earthquake.

The present invention has been made in view of such a point. An object of the present invention is to incorporate a vibration control device into a reinforced concrete column or wall, and to cause interlayer deformation in a building during an earthquake, Even if a shear force is applied, the mounting part of the vibration control device is not easily damaged, has sufficient mounting strength, can reliably absorb the earthquake input energy, and is easy to manufacture. An object of the present invention is to provide a material, a vibration control structure, and a method of constructing the same.

Another object of the present invention is to provide a good energy absorption capacity at the time of an earthquake without deformation due to the weight of upper columns and walls even when a low yield point panel steel is used as a vibration control device. Building materials for vibration control that can be demonstrated
An object of the present invention is to provide a vibration control structure and a method of constructing the same.

Still another object of the present invention is to provide a seismic control system for constructing columns and beams made of reinforced concrete, which eliminates the need to support a concrete formwork by shoring or the like, and saves time and effort. It is an object of the present invention to provide a building material, a vibration control structure, and a method for constructing the same.
