In recent years, high response performance is required from viewpoint of the BCP. A vibration control structure of a
medium-low-rise building is increasing, not only a high-rise building. Therefore, the development of the vibration control structure
building system suitable for medium-low-rise buildings is desired. In this paper, the response performance is planned to improve by
changing the beam-end to low-rigidity for extending the displacement of the elastic limit. Also, it was showed that it can reduce the
shear force and damage to main the structure, through the time history response analysis with the stiffness of beam-end and amount
of damper as parameters.
