A two-story, two-span by two-bay frame was set up on E-Defense shaking table, and curtain walls made of metal sashes and glasses were attached with typical connection details. In a series of tests, seismic responses of a high-rise building were reproduced in the frame. First, damage of the curtain walls in expected seismic responses (the maximum inter-story drift angle is 0.02 rad) was observed. The possibility that the curtain walls come off and drop from the frame was also considered in an ultimate deformation range (the maximum interstory drift angle is 0.04 rad). Source

A four-story RC building is tested by using the E-Defense shake-table facility in order to verify the assessments based on AIJ recommendations as well as in order to examine its performance given by the newer Japanese code. The building consists of moment frames and multi-story walls. Ground motions recorded in the Hyogoken-Nanbu earthquake are used, and the intensity of shaking is gradually increased. Story drift responses of the building reach more than 0.03 rad. Finally, multi-story walls suffer flexural failures at the critical sections of the first story. Beam-column joints suffer shear failures, while beams and columns exhibit flexural yielding. Source
