This paper reports on a large-scale shaking table test of a high-rise steel building. The building specimen is a 1/3-scale 18-story steel moment frame designed according to design specifications used in the 1980s and 1990s. The input motion is a long-period and long-duration strong ground motion. The main cause of the collapse of the test specimen was the extension of the fractures of the lower flanges at the beam-ends of the lower stories. Furthermore, the relationship between the changes of the vibration characteristics and the extension of the structural damages was presented.
