Large Scale Shaking Table Tests for High-Rise Buildings: New Projects of E-Defense

No actual data based on observations are available for high-rise buildings subjected to long-period ground motions. In order to acquire realistic data on the damage, a series of large-scale shaking table tests were conducted in E-Defense, a large shaking table facility. The paper presents ongoing high-rise building projects at E-Defense. First, the earthquake threats of Japan and the backgrounds of E-Defense are introduced. Second, a series of shaking table tests for the seismic performance of building structures are presented. In these tests a number of cyclic deformations are applied to a steel moment frame. Third, a shaking table test focusing on the safety of rooms is presented. The test reproduced large responses of floors, characterized by large velocities and displacements.

The seismic capacity of high-rise steel buildings is a matter of concern, particularly when they are subjected to long-period ground motions. A series of large-scale shaking table tests conducted at E-Defense disclosed fractures in beam-to-column connection s and represented the effects of retrofit for such high-rise steel buildings. Damage to office and residential rooms was also reproduced.
