A towering reinforced concrete(R/C) smokestack of 200m in height of an LNG thermal power plant constructed on a reclaimed land in Osaka bay area were strongly excited during the 1995 Hyogoken Nanbu earthquake. 12 sets of earthquake motion records including either this strong motion or weak motions before and after this event are analysed and studied at the standpoint of changes in predominant periods of the ground and the smokestack. For the ground, fundamental frequency during the strong event is lower than those before the event and those after the event are equal to before. Otherwise, for the smokestack, fundamental frequency during the event is much lower than those before the event, but those after the event are lower than before. The ground is reversible, but the smokestack is nonreversible. Nonlinear behavior of the ground and the smokestack are discussed not only on measured data analysis but also on numerical analysis results by a Penzien-type model adopted for the design of this smokestack.
