地震によって損傷を受けた鉄骨建築物の耐震安全対策に関する実験研究 Experimental Study on Seismic Measures for Steel Frame Buildings damaged by Past Earthquakes 防災科学技術研究所 ボウサイカガクギジュツケンキュウショ National Research Institute for Earth Science and Disaster Resilience 防災科学技術研究所 ボウサイカガクギジュツケンキュウショ National Research Institute for Earth Science and Disaster Resilience 兵庫県南部地震において、新耐震基準により設計された鉄⾻造建築物の梁端溶接接合部の破断を伴う被害が報告されました。一方、外装材の損傷が⽐較的軽微で、外観目視調査だけでは接合部の損傷検知が困難な事例も数多く確認されており、未検知の損傷が残されている懸念が指摘されています。このような背景を基に、兵庫県と神戸大学との共同で、1) センサーを用いた鉄⾻建築物の健全度推定技術の開発、2) 南海トラフ巨⼤地震発生時の、過去の地震で柱梁接合部が損傷した鉄⾻建築物の被害程度推定を目的とした実験研究を行いました。実験では，実⼤3階建て鉄⾻建築物の⼀部を取り出した試験体に、JR鷹取波や神⼾市における南海トラフ地震想定波等を入力しています。 In the Hyogo-ken Nanbu Earthquake, there were cases of damage associated with the rupture of beam end welded joints in steel-framed buildings with new seismic design standards. On the other hand, there were many cases where the damage to the exterior materials was relatively minor, and it was difficult to detect damage to the joints just by visual inspection of the exterior, and there were concerns that undetected damage remained. In light of this background, this experimental research was conducted with the aim of developing technology to estimate the soundness of steel-frame buildings and estimating the extent of damage to steel-frame buildings damaged in past earthquakes when the Nankai Trough Mega Earthquake occurs as collaboration with Hyogo Prefecture and Kobe University. In the experiment, a full-scale three-story steel-framed building was constructed, and the JR Takatori motion and expected motion in the Nankai Trough earthquake in Kobe area were input to the building. The measurement data and images obtained in this experiment are available. データ取得：2013年 Data acquisition period : 2013 お問い合わせ：asebi@bosai.go.jp inquiry： asebi@bosai.go.jp 防災科学技術研究所 National Research Institute for Earth Science and Disaster Resilience 2015 dataset 10.17598/NIED.0020-E201303 https://nied-repo.bosai.go.jp/records/7202 https://asebi.bosai.go.jp/ LOGIN Page for Registered Users
