The Random Decrement (RD) technique is applied to vibration observation data of a building excited by a weak seismic ground motion. Estimates are made of the damping ratio and natural frequency for 7 buildings of the University of Tokyo. Data are obtained with IT strong-motion seismographs installed inside buildings of the University. Then, a Single Degree Of Freedom (SDOF) system analysis is carried out. The simplest building for which the primary mode dominated is selected, and parameters estimated using the RD technique are sent to the SDOF system. The results obtained with the RD technique and the SDOF system analysis are compared, and the accuracy of the estimated data are verified. Finally, problems related to establishing the method for estimating the damping ratio using weak seismic ground motion are discussed.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72502","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Toyoda, Takahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"72503","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takano, Kiyoshi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032412","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科建築学専攻"},{"subitem_text_value":"東京大学情報学環/地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"豊田, 尭博"}],"nameIdentifiers":[{"nameIdentifier":"72500","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鷹野, 澄"}],"nameIdentifiers":[{"nameIdentifier":"72501","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"IHO88101.pdf","filesize":[{"value":"5.1MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IHO88101.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32412/files/IHO88101.pdf"},"version_id":"9e05781d-6c7c-4867-9641-8f104dbbced5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"damping ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"natural frequency","subitem_subject_scheme":"Other"},{"subitem_subject":"Random Decrement technique","subitem_subject_scheme":"Other"},{"subitem_subject":"weak seismic ground motion","subitem_subject_scheme":"Other"},{"subitem_subject":"SDOF system","subitem_subject_scheme":"Other"},{"subitem_subject":"IT strong-motion seismograph","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"弱い地震動を用いた建物の減衰定数の推定 : 東京大学の建物を対象として","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"弱い地震動を用いた建物の減衰定数の推定 : 東京大学の建物を対象として","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4552","4554"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-06-15"},"publish_date":"2016-06-15","publish_status":"0","recid":"32412","relation_version_is_last":true,"title":["弱い地震動を用いた建物の減衰定数の推定 : 東京大学の建物を対象として"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:16:25.866670+00:00"}
