振動台加振実験による鋼構造2 層純骨組の弾塑性地震応答の推定 Estimation of Elastic-Plastic Earthquake Response of Two-Story Steel Pure Frames under Shaking Table Tests 木曽, 翔太 キソ, ショウタ 岩井, 哲 イワイ, サトシ Kiso, Shota Iwai, Satoshi 524.91 steel pure frame shaking table earthquake wave pattern elasto-plastic response analysis restoring-force characteristics application/pdf The simple one-story and two-story steel pure-frame specimens were tested under the earthquake excitation increasing the maximum acceleration level, using the shaking table. The test structures consist of two columns with rigid roof and rigid floor. This research aims to investigate how the characteristic of the input earthquake wave charges the elast-plastic behavior of the frame specimen, compared with the results of the experiment and dynamic earthquake response analysis. Two types of analytical model of restoring force characteristics are employed, which are bi-linear and tri-linear models, to compare the maximum load-carrying capacity and the maximum storydisplacement of the test model. It is found that the maximum acceleration level, in which the story-displacement response of the frame get into plastic range, is influenced by the periodical property of the input earthquake wave. departmental bulletin paper 広島工業大学 2009-02 VoR application/pdf 広島工業大学紀要. 研究編 43 271 277 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/795/files/kiyo43271.pdf https://it-hiroshima.repo.nii.ac.jp/records/795 jpn
