Those are movement-limiter attached to a shoe and bridge restrainers using tie plates. This article examines seismic effects of bridge restrainers through investigation of damages during the Great Hanshin-Awaji Earthquake，and figures out an irrational point of current design code. Impact response behavior of the seismic bridge-tie system is also found out through analytical study utilizing three-dimensional finite element code LS-DYNA3D for analyzing the large deformation dynamic response of inelastic solids. Falling body analysis of the complete bridge and seismic tie system in the gravity field and high-rate failure analysis of steel tie-plate has been done by using a contact-impact algorithm that allows sliding along material interfaces and by using strain rate effect.","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":"長嶋, 文雄"}],"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":"20024-061-005.pdf","filesize":[{"value":"973.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20024-061-005.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/5579/files/20024-061-005.pdf"},"version_id":"95ca87bf-156c-4633-8747-537bef328a68"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Earthquake Disaster","subitem_subject_scheme":"Other"},{"subitem_subject":"Seismic Bridge Restrainer","subitem_subject_scheme":"Other"},{"subitem_subject":"Earthquake Engineering","subitem_subject_scheme":"Other"},{"subitem_subject":"Hyougo-ken Nanbu Earthquake","subitem_subject_scheme":"Other"},{"subitem_subject":"Impact Response Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Strain Rate Effect","subitem_subject_scheme":"Other"},{"subitem_subject":"地震被害","subitem_subject_scheme":"Other"},{"subitem_subject":"耐震連結板","subitem_subject_scheme":"Other"},{"subitem_subject":"地震工学","subitem_subject_scheme":"Other"},{"subitem_subject":"兵庫県南部地震","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃応答解析","subitem_subject_scheme":"Other"},{"subitem_subject":"歪み速度効果","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":"阪神・淡路大震災における橋桁間の耐震連結装置の被害および衝撃応答解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"阪神・淡路大震災における橋桁間の耐震連結装置の被害および衝撃応答解析"}]},"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":"5579","relation_version_is_last":true,"title":["阪神・淡路大震災における橋桁間の耐震連結装置の被害および衝撃応答解析"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T17:13:35.744763+00:00"}
