Behaviors of Nonstructural Components in Seismic Responses of High-Rise Buildings - E-Defense Shaking Table Test

Abstract eng:
This research focuses on the nonstructural components in high-rise buildings subjected to large seismic responses. A serious of large-scale shaking table tests is conducted by using E-Defense shaking table. For the tests, a partially extracted two-story full scale frame system is adopted to reproduce the seismic responses of high-rise buildings. The two-story frame is 8.6 m x 10.6 m in plan and the story height is 3.4 m. Since the two stories are built on a concrete slab supported by rubber isolators, the system is able to vibrate with the long period of about 2.8 sec and is able to produce long duration events without exceeding the capacity of E-Defense accumulator system. The frame is appropriately designed to generate the drift angle of more than 0.01 rad elastically. The furniture incorporated in the sectioned interior spaces falls down and slides around. The exterior walls installed in the frames show small damage.
