3次元フレーム解析モデルを用いた超高層免震建物の時刻歴風応答解析一方向入力と三方向同時入力による免震層応答の比較

摘要

本論文では，超高層免震建物を対象とした3次元フレームモデルを作成し，台風シミュレーシヨンによる結果を用いた時刻歴風応答解析を行なった.作成した3次元フレームモデルに対し，一方向風荷重入力時の免震層変形と，実際の強風イベントを想定した，捩れ成分を含んだ三方向同時風荷重入力時の免震層変形を比較し，その整合性について検討を行なった.以下に，本論文で得た知見を示す.%In recent years, as a result of the growing interest in seismic isolation structure and technological progress, opportunities for seismic isolation structures to be adopted for super high rise buildings are increasing. However, there are few examples of elasto-plastic response analysis using a three-dimensional analysis model due to the time constraints to be analyzed and the complexity of the external force. Therefore, in this analysis, using a three-dimensional analysis model, the purpose is to compare the response of the seismic isolation layer at the time of one-way external force input and input of coupled three-dimensional external force and to be an index of time history wind response analysis in the future.
