Abstract |
In this study, dynamic responses of high - rise buildings were analyzed through the change of horizontal stiffness and yield strength among
characteristics of seismic isolation system by applying middle - layer seismic isolation system to high - rise buildings of 120m height. As a
result in order to prevent the displacement of the isolation layer and to control the maximum torsion angle, it is possible to appropriately
control by increasing or decreasing the horizontal stiffness and the yield strength. However, depending on the maximum torsional angle and
the hysteretic behavior of the seismic isolation system, excessive yield strength and horizontal stiffness increase may induce the elastic
behavior of the structure and amplify the response. Therefore, it is considered that it is necessary to select the property value of the
appropriate isolation device. |
