Particular attention was paid to the non-stationary characteristics of earthquake motions. First the running power spectrum density function (RPSD) was estimated by dividing the whole earthquake duration into certain “stationary” segments. Then the computed RPSD was described as a 2-dimensional evolutionary spectrum on the time-frequency plane. Next，the described RPSD patterns for various types of strong earthquake records were classified into 36 typical pattern models by paying attention to the following representative information of the RPSD; (1) number of peaks of the RPSD，(2) degree of development of power strength on the time-frequency plane and (3) relative location of peaks of the RPSD. Finally a new earthquake simulation technique was proposed by using the ealculated characteristics and phase-increment distribution characteristics of earthquake motions presented by Ohsaki.","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":"鈴木, 浩平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"戸澤, 祥二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青木, 繁"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-12"}],"displaytype":"detail","filename":"20024-008-008.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-008-008.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/4749/files/20024-008-008.pdf"},"version_id":"cdb9bb9f-0e10-4dfd-903d-6b060f6b5d17"}]},"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":"地震動特性のパターン化と耐震設計への応用に関する基礎研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地震動特性のパターン化と耐震設計への応用に関する基礎研究"}]},"item_type_id":"3","owner":"3","path":["772"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-26"},"publish_date":"2016-10-26","publish_status":"0","recid":"4749","relation_version_is_last":true,"title":["地震動特性のパターン化と耐震設計への応用に関する基礎研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T17:55:43.361295+00:00"}
