Behavior of Exterior Curtain Wall of High-Rise Buildings Against Large Story Drift by Long-Period Earthquake Ground Motions

Abstract eng:
Recently, the possibility that a high-rise building generates the vibration with large displacement amplitude against the long-period earthquake ground motions by the ocean trench type and against the near fault earthquake ground motions has been indicated. Though an exterior curtain wall (called the following CW) of a high-rise building has been designed for various external force, the behavior and process to failure of CW with large story drift has not been clarified yet. In this paper, the dynamic behavior of CW in the large deformation was observed by the shaking table test using full-scale specimen. As a test specimen, high-rise building of 30 stories with average earthquake resistance performance is assumed. Authors built the testing system of 2 stories on, which could reproduce story drift of the high-rise building was reproduced, and the largest floor acceleration was reproduced in the 2nd floor. Dynamic behavior was similarly tracked even in full-scale shaking table test against the large deformation of story drift angle of 0.05. The response acceleration data was recorded, in- and out-plane direction which affects CW in real time. The dynamic behavior of CW in the large deformation was clarified by dynamic experimental tests with full-scale specimen.
