The purpose of this study is to investigate a method of quantitative estimate of the elastic input energy Eie and hysteretic energy Ehp of SDOF structure subjected to strong earthquake motions. In this study, numerical response analyses for bi-linear SDOF structures were carried out by the use of artificial earthquakes and recorded ones. From the examination of analytical results, it is found that a good correlation can be seen between the energy response spectrum Es for Eie and Ehp and effective Fourier amplitude spectrum Fse for each in put earthquake. Also the difference in values for the ratio of the square root of the Esk to Fsek, at any natural period Tk, is seen to be substantially reduced amongst the earthquakes. Considering these results, the authors derived re キーワード(英): - 記事区分 - 区分     論文集
