The area was classified into 3 sub-areas (A，B，and C) with different earthquake damage of structures，where A is the heavy damage area with JMA-seismic intensity of 7 or more，B is the small damage area，and C is liquefaction area. The resonant frequencies of the surface ground of the area were obtained from 2.5 Hz to 4.5 Hz. The resonant frequencies of sub-area A were concentrated in about 3.0 Hz，and those of sub-area B were higher than A，and those of sub-area C were lower than A. The resonant frequencies of this area were estimated by 1-D multiple refrection theory using boring test soil data，which agreed well with the microtremore measurement data. Moreover，Soil profile (the ground constants and the depth of the surface ground) of this area were identified reasonably. The results agree well with the boring by the developed identification method using the microtremore measurement data.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"postprint","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京都立大学都市研究センター"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00134354","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03863506","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岩楯, 敞広"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大岡, 晃"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荏本, 孝久"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-17"}],"displaytype":"detail","filename":"20024-061-002.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-061-002.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/5576/files/20024-061-002.pdf"},"version_id":"ebbfe546-00c8-4ec9-8325-cd069f6d612b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Earthquake Damage","subitem_subject_scheme":"Other"},{"subitem_subject":"The Great Hanshin-Awaji Earthquake","subitem_subject_scheme":"Other"},{"subitem_subject":"Microtremore Measurement","subitem_subject_scheme":"Other"},{"subitem_subject":"Seismic Response Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Identification Method","subitem_subject_scheme":"Other"},{"subitem_subject":"地震被害","subitem_subject_scheme":"Other"},{"subitem_subject":"阪神・淡路大震災","subitem_subject_scheme":"Other"},{"subitem_subject":"常時微動観測","subitem_subject_scheme":"Other"},{"subitem_subject":"地震応答解析","subitem_subject_scheme":"Other"},{"subitem_subject":"同定解析","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":"芦屋・西宮地区の表層地盤の微動特性と地震被害の関連性の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"芦屋・西宮地区の表層地盤の微動特性と地震被害の関連性の検討"}]},"item_type_id":"3","owner":"3","path":["1321"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-31"},"publish_date":"2017-03-31","publish_status":"0","recid":"5576","relation_version_is_last":true,"title":["芦屋・西宮地区の表層地盤の微動特性と地震被害の関連性の検討"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T17:13:42.440027+00:00"}
