The natural period and the damping ratio of buildings depend on the amplitude of vibration. The authors have studied that for RC buildings. In this paper, 8 high-rise steel buildings were studied. Both the natural period and the damping ratio are dependent on the vibration amplitude of the building. In this paper, the damping characteristics during the 3.11 earthquakes were studied, especially.
