露出柱脚付低層鋼構造物の地震時応答性状と柱脚挙動について ――その3　回転バネを設置した場合―― A SEISMICRESPONSE OF FRAME & COLUMN-BASE FOR LOW-RISE STEEL STRUCTURE WITH EXPOSED COLUMN-BASE —— part 3 Steel structure with rotational springs —— 山西, 央朗 ヤマニシ, テルアキ Yamanishi, Teruaki exposed column-base rotational spring rotational stiffness time history analysis frame response application/pdf Exposed column bases employed in middle-rise steel structures can be designed and analyzed using simplified models of restoring force characteristics. The models are described with maximum bending strength and elastic rotational stiffness of the exposed column base, but without additional bending resistant capability of column axial force. This paper describes response analyses of structures with column bases of full and simplified models and the following conclusions are obtained.|The response results of the simplified models are in good agreements with those of the full models. The worst results are overestimated by 30%. Thus, simplified models can be used for rational design of steel structures. departmental bulletin paper 広島工業大学 2018-02 VoR application/pdf 広島工業大学紀要. 研究編 52 133 141 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/1056/files/research52_133-141.pdf https://it-hiroshima.repo.nii.ac.jp/records/1056 jpn publisher
