|Abstract:||The understanding of amplitude-dependent dynamic properties is useful to forecast the structural performance under aftershocks. The authors have proposed an analytical method that uses only a main shock response to evaluate the amplitude-dependency of natural frequencies for steel buildings. The effectiveness has been verified by the vibration data recorded at an actual 29-story steel building in Tokyo under the 2011 Great Tohoku Earthquake. To investigate its effectiveness and practicability more, this paper applies the same method to four other steel office buildings that were excited under the Tohoku Earthquake: a 15-story building in Sendai, 20-story and 21-story buildings in Tokyo, and a 23-story building in Yokohama. These application examples illustrate the high effectiveness of the proposed evaluation method.|
